Well, the scripture reading today will be from Mark chapter 11. You can find that on page 1573. I promise you that I wasn't trying to steal Reverend Miller's thunder by skipping a couple chapters, because we've been going through Mark. I think we were in Mark 9, 10, I believe, last. But just by the Lord's providence, it was a passage that was assigned to me at Mars. So the Lord wants us to review it, and I think this evening we also are going through Mark in advance. The Lord is wanting us to review these things. So we're gonna be at verse 11, we're gonna start, Mark 11, starting at verse 11 and going through to 25. Jesus entered Jerusalem and went to the temple. He looked around at everything, but since it was already late, he went out to Bethany with the 12. The next day, as they were leaving Bethany, Jesus was hungry. Seeing in the distance a fig tree and leaf, he went to find out if it had any fruit. When he reached it, he found nothing but leaves, because it was not the season for figs. Then he said to the tree, may no one ever eat fruit from you again. and his disciples heard him say it. On reaching Jerusalem, Jesus entered the temple area and began driving out those who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves, and would not allow anyone to carry merchandise through the temple courts. And as he taught them, he said, is it not written, my house will be called a house of prayer for all nations? But you have made it a den of robbers. The chief priests and the teachers of the law heard this and began looking for a way to kill him, for they feared him because the whole crowd was amazed at his teaching. When evening came, they went out of the city. In the morning, as they went along, they saw the fig tree withered from the roots. Peter remembered and said to Jesus, Rabbi, look, the fig tree you cursed has withered. Have faith in God, Jesus answered. I tell you the truth. If anyone says to this mountain, go, throw yourself into the sea, and does not doubt in his heart, but believes that what he says will happen, it will be done for him. Therefore, I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours. And when you stand praying, if you hold anything against anyone, forgive him, so that your Father in heaven may forgive you your sins. Let's pray together. Our Father in heaven, this is your word. It speaks truly to us and clearly, though at times, because of a slowness of heart and mind, we get confused, and we pray that today this would become clear, that Christ would be preached directly to our hearts. So we pray for the spirit to receive. And for the speaker, we pray for clarity of mind and calmness of nerves. We pray this in your name, amen. Well, up to this point, we've been seeing, as we've been going through Mark, our pastor has been pointing out to us, the spiritual battle that's been taking place between all of these encounters that Christ has. And for a second, if you will imagine this battle, spiritual battle, as the kingdom of darkness, and John kind of puts it this way, that the light has come. So you can imagine a globe surrounded by storm clouds, And when Christ is born, a light touches down. But that light is really more like a lightning bolt. And when it hits, the kingdom of light starts to spread. And all of Christ's ministry is what we see. He's healing, he's pushing back, he's casting out demons. And in a lot of ways, what we're approaching here in the temple, this is the heart of the storm. It was interesting this week, it was brought up by one of my professors that in Luke, there's a section that we've reached right now where in Reverend Miller's series, where Christ turns his face to Jerusalem and he starts making his way to Jerusalem. And in Luke, there's an additional ten or so chapters that happens between now, where we are in Reverend Miller's sermon series, and where we are this morning. And so it is interesting that Mark, his gospel is really characterized by the importance. He says immediately, immediately, immediately. And it gives you this idea of this battle happening between Christ and the kingdom of darkness. Now Christ is, it's not really much of a battle in a way. Christ is coming and conquering, right? And so here we have Christ arriving, again, like I said, at the kind of center of the storm cloud. But the interesting thing is, where is that, the center? We find that it's in Jerusalem, on the mountain of God. And even more so in the temple of God. So could the question be asked, how? How did that happen? Well, that's our first point we wanna go over. How did that happen? We wanna look at when Christ goes in and sees everything, what is he seeing? As this battle is set up, what does this battle look like? And then our second point is really the exciting part. It's that battle that happens where Christ enters the temple. But I also want to point out to you a common theme that goes through, and I think this is illustrated by the story of the fig tree that Christ uses to teach, and that is the hypocrisy of Israel, that they outwardly worship the Lord, that they give their sacrifices, that they speak words of repentance, but inwardly, it's pride. Inwardly, it's hatred for the Lord. We see that in the way that they reject Jesus. They seek to kill him. And we find that only Jesus can cleanse our heart. And we want to apply this to ourselves. The theme, beware the hypocrisy of the heart. Repent and believe. Point number one, beware the hypocrisy of the heart. The devil makes his den. As I said, we're gonna set up what we're seeing. And number two, the devil makes his den. Until Jesus storms in, repent and believe. So point number one, beware the hypocrisy of the heart. The devil makes his den. Now if you look at me, look with me, at verse 11, Jesus enters the Jerusalem. So we're thinking about the triumphal entry has just taken place. And where does Christ go first? Immediately he goes to the temple. And it says here, he looks at everything. What is everything? Well, before we get to that, I think it's important that we remind ourselves, what is the temple of God? And the temple of God, as he said, is a permanent place for God's dwelling. It's a mediatorial location amongst the people of Israel. And the people who were destined or who God appointed to take care of the temple were the priests. Their job was to offer on behalf of the people, they are the representatives of the people. They represented all Israel. They would give forth offerings in repentance for the people and they would teach But here we have the temple representing Israel. And so Christ, he goes immediately to the temple, and he surveys. And we're to get back to what he sees exactly. But if you hear here that at the end of 11, he leaves. And the next morning, we have this teaching of the fig tree, which can be a little confusing when you're reading it. But I think that there are two important things to keep in mind. to help translate it, to help understand it. The first point is at the end of verse 14. It says, and his disciples heard him say it. We have to remember that this is not reactionary by Jesus, it's not haphazard, that when he uses the fig tree, he's using it purposefully to teach them what's about to happen. He's saying to them, watch me, watch what I'm doing closely, because he's about to do this in the temple of God in just a moment. The other thing that we need to know, not only is it not haphazard, the fig tree, it's very purposeful, but the second thing to interpret it is that, and maybe you could think of many passages in the Bible where a tree is used to represent either the people of God or a person of God, and here again in the Old Testament, oftentimes Israel is represented by a fig tree, and God many times will not find fruit, and he will judge the people, but there are times where he finds fruit, And you hear the warmth and the love of God when he sees fruit on the tree. So those are the two key points that we need to remember. So let's look at what Christ is saying. He paints a picture here for his disciples, because it says that Christ is hungry, and he approaches the tree. The tree has big green leaves, and the green leaves here are telling whoever's passing by that there's fruit. Now, in our culture today, we just go to the grocery store and we can easily find fruit. But back then, it didn't work that way. And so people would be more in tune and understanding when things were ripe. And they could see on this tree that this tree would be offering fruit given by the leaves that it had. So people that were hungry, this tree would call out to them, look at my leaves, there's fruit here, come to me and be satisfied. But as we see too, Christ left hungry. And for anyone who approached this tree, This tree was nothing but leaves, and it says it in a negative way, as if it was worthless, a worthless tree that lies. Now again, I'll point you to the fact that Christ is not doing this randomly, but that he's pointing to Israel. Okay, what is Israel doing? And when I say Israel, I'm talking specifically about the representatives of Israel, the high priests. Okay, so when we look at the leaves of the tree that calls without there being any inward fruit, We see that as well in Israel. And I think this is so important. And this was a lot of fun for me to research this. And if you have time later, maybe you can look online for what Herod's temple was, how grand it really was. They have models and animations. It was beautiful. But all of that was outward. Herod's temple took 10,000 workers to build. The court of the Gentiles alone was the equivalent of 30 soccer fields side by side, 30. And we know Christ cleanses that area of the temple. When you're looking at it from an aerial perspective, so you can see the whole court, people would be smaller than ants. And we know also in AD 70 that the temple was destroyed by the Romans. But today, there still are stones at the foundation. And the largest stone that they have, which was brought from a quarry close by, the largest stone is 600 tons. It's one stone that people had to bring that down to the temple. So it's quite a structure. And the temple itself had a crown of gold. Surely the people were thinking, there must be fruit here. We are fruitful. Look at the grandeur of the temple. If there was a building that's worthy to hold God, this would be that building. And perhaps also you're aware, this past year I looked up statistics for the Super Bowl. Because this wasn't any time of year. The Passover was a week away. And Josephus, a historian, recorded that hundreds of thousands of people would be coming to Jerusalem during this time. The Super Bowl had 70,000 people in attendance. And if you're aware, they shut down cities for those kind of things. And it could be dangerous with that many people. So here, if we compare it to that, many more times the people were here. So they must have been thinking, we're doing something right. And everyone might have been thinking that. This is a fruitful temple. But these are all outside things. We know that they had moved a market in, we read that in verse 15, but we also are familiar now with how people tend to spin things. We always put a spin on them. So they might have been thinking, well traditionally up to this point there was a market that was across the valley on the other side where you could go and you could purchase animals to sacrifice. They might have been thinking, or at least spinning it, Well, let's bring that market in so people that are lame or that are hard for them to walk around will have the animals and things like that easier for them to access. Let's bring it in the temple. Now, of course, the high priest would know that would profane the temple. But again, they could spin it. We're fruitful. Look at us. We're generous. And it talks about here that people will be walking through the temple because it had become a spectacle for people to see, a tourist attraction. And even that. The high priest might be thinking it's our evangelism plan. We have people coming in and coming out. It's a house, a temple for all people. Of course, again, that profaned it and people weren't able to worship in that area of the temple. But we could spin it, right? We can always spin things and we can always look at things that we pretend are fruit, but really these are just outward leaves. And Christ comes and he inspects and he pushes past the leaves and he sees that there's no fruit. So the question I think we need to ask is what is the fruit that God was looking for in Israel? Hundreds of thousands of offerings were going up, but no heart. In verse 17, we hear the purpose of the temple. He says, my house will be called a house of prayer for all nations. Now that's a reference to Isaiah chapter 56, talking about the Gentiles and how the Gentiles would be taken in to be saved. But I wanna focus more on a reference. And if you have time, either this afternoon or this week, maybe you can read this chapter. It's 1 Kings chapter eight. It's a wonderful chapter. And it's Solomon's prayer of the dedication to the temple. And it's so important because we hear there, he talks about the reason for the temple. Well, first of all, his temple was grand. But one of the first things he says to the Lord is that we know that you can't dwell in a building. What building can hold you? So he's not looking at the outward aspect of things. He knows that it's inward. Even the heavens of heavens can't hold you, he says. And then he goes on in his prayer to say, he repeats the same thing. He says, if the people of God are dying in wars, he says, hear our prayers and forgive us. If the harvest is dry and we don't have any food, hear our prayers of repentance and forgive us. And he goes on and on. If you can read that later this week, 1 Kings 8, you'll see, hear and forgive, hear and forgive, hear and forgive. That is the fruit that Christ is looking for. The fruit of repentance. So even as they were giving offerings for repentance, their heart was not there. Because they said, we have the outward things, we have the temple. And if you can also remember that John the Baptist, early in his ministry, when he was baptizing the wilderness, and the Pharisees and the rulers of the Jews went out to see him, what did he say? You brood of vipers, who told you to come out here? What is it he said, what are we looking for? You need a bare fruits of repentance. It's the same men that we see here. This is what the Lord is looking for, fruits of repentance. So much blood was shed in those animals, but no heart. Many outside signs, but no inward change. And now in verse 14 of the fig tree, we read there's judgment. May no one ever eat fruit from you again. Yes, this was judgment on Israel. And as we know, and a little bit later he talks about this, that the temple will be destroyed, But this is judgment on Israel because the people who represented Israel, and Israel as a nation, had forgotten God. And just before we move on to the next point, I want to point out this, it's very visual here. It's almost visceral, this idea of this temple, how grand the temple was, how huge the walls were. Could you imagine when they built this? If we're thinking about the spiritual battle that was happening, the kingdom of darkness, this was like building a fortress for Satan. And watching all of the 10,000s of people that built it, it was like an army. And as they brought those massive stones down and as the cranes lifted them up, the picture of that is like an army against the Lord. Machines of war. But it wasn't just that Satan had built high walls, but that the infestation was deep. And much more so that was important. The high priests. So as man had forgotten God and Satan had set up shop, and the temple of God. Could we ask what hope there would be for man? And I know that you know the answer to that. It's the Sunday school question, isn't it? It's Jesus. But let's talk about that in the second point. The devil makes his den, yes, but until, I should say, Jesus storms in, repent and believe. And just as we go on to that, I want to pause for a second. I want you to ponder the question because we ultimately need to ask ourselves this question. Do we bear fruits of repentance? Or do we produce leaves? I think the bigger question is how? How do we bear fruits of repentance? What does it look like? Is it emotion? Is it just sorrow? Is it being particularly sad? Is it a particular doctrine that we hold? Is it the fact that we pray before our meals? There's so many things that are good and healthy, but those things in and of themselves can even become leaves. So let's think about that. How do we bear fruits of repentance? Let's move on to point number two. A little bit before this, in the ministry of God, I want to draw your attention to a story where Christ is casting out a demon. And the Pharisees are there, and they accuse Christ. They say that he's casting out demons by the power of demons, which is kind of a ridiculous statement. I was trying to explain it to one of my kids last night, and they didn't understand it. And that's good, because it doesn't really make sense, that argument, to cast out demons. And Christ calls that out, and he says, really, that you're making no sense. Because if demons cast out demons, then what kingdom would there be? Because they would be destroyed. But then he says that the strong man must be bound, and he's talking about Satan, then he could plunder his goods. And I want to be honest with you, that the whole Gospel of Mark, when I talked about the kingdom of darkness and light coming down, and Christ spreading that light and taking the kingdom back, that's the binding of Satan. the binding of the strongman. He's been doing that. But now in the temple cleansing, we get to see that in a more physical way. So let's read 15 through 18. On reaching Jerusalem, Jesus entered the temple area. And if you notice here, there's a lot of times where Jesus teaches or he asks questions, not here. You can imagine how sudden this would be. Jesus entered the temple area and began driving out those who were buying and selling there. Not just those that were selling, but those that were buying. He overturned the tables of the money changers and the benches of those selling doves. Just a quick comment, in the original Greek, when he's talking about overturning the tables, that was the word for catastrophe. Literally, that's the word that they used, catastrophe. And would not allow anyone to carry merchandise through the temple courts. And that's why I said those were people that would kind of cut through to just be in awe of the temple. And as he taught them, he said, Is it not written, my house will be called a house of prayer for all nations? But you, talking to the chief priests, you have made it a den of robbers. When you look at this picture, why is there no opposition? Again, we think about how large 30 soccer fields, how many people there might have been. It's not Passover yet, but there are probably thousands of people, and Christ clears them out. If you think about that today, if someone tried to do that, wouldn't he be stopped? I mean, think about the money that would be made there. Yes, certainly he would be stopped. No one tries to stop him, and why? because Satan is bound. Satan has been bound. And the chief priests, basically, it's like they're standing in the corner as Christ accuses them in front of the people. These are the people, he says later, don't pray like these people. In a way, when he comes, he sets up shop in the temple and he teaches them. That's the next section if you read the next couple chapters. He is there teaching and many times he points to them and says, don't do what they do. Do everything but what they do. And they have to sit there and accept it because Satan has been bound, they have been bound. And if I can, I'd like to read If you'd like to turn with me to Malachi chapter 3, it's 1490 in your Bibles, Malachi chapter 3, 1490. But when you think about the size of the temple, you may ask, what man could clear such a temple? So many animals, so many people, such a scale, it's hard for us to imagine that. But in Malachi chapter three, you'll read the first six, five verses. This is a prophecy even of this, temple cleansing. Chapter three. See, I will send my messenger who will prepare the way before me. And listen to this. Then suddenly, the Lord you are seeking will come to his temple. The messenger of the covenant whom you desire will come, says the Lord Almighty, But who can endure the day of his coming? Who can stand when he appears? For he will be like a refiner's fire or launderer's soap. He will sit as a refiner and purifier of silver. He will purify the Levites and refine them like gold and silver. Then the Lord will have men who will bring offerings in righteousness. And that is what Christ does. He clears the temple and prepares it again for worship. And the offerings of Judah and Jerusalem will be acceptable to the Lord as in the days gone by, as in former years. So I will come near to you for judgment. I will be quick to testify against sorcerers. And brothers and sisters, this is exactly what he does after he cleanses the temple. He then judges the people. He judges the leaders of Israel. So I will come near to you for judgment. I will be quick to testify against sorcerers, adulterers, and perjurers, against those who defraud laborers of their wages, who oppress the widows and the fatherless, and deprive aliens of justice. But do not fear me, says the Lord God Almighty. So I'll put the question before you again. What man could clear such a temple? Whereas the question we should be asking ourselves is what man could stand before such a God? Yes, this is a divine act. Christ is revealing himself as God. And the first thing that he does, it says, if we go back to Mark, it says he teaches. 17, and as he taught them. And again, I wanna bring that before you, that that was one of the acts of the high priest, to offer a sacrifice for sins, but they would teach the people the law of God. And this is what Christ, our true high priest, is now doing. We know that he will give the ultimate and the final sacrifice of himself, but here he teaches. And again, if you read through the next couple chapters, that's what you're gonna see. He continues to teach the people. And what does he teach? What's the first thing? You have made it a den of robbers. It should be a house of prayer for all nations, but you have made it a den of robbers. It's an act of judgment, just like for the tree. The phrase, den of robbers, is taken from Jeremiah chapter 7, and I think that helps us when I read that. That helped me to understand better what that means, because den of robbers, I immediately thought, well, now they've set up shop, they're selling to the people, they're selling them the animals, they're exchanging money, and they're not fair about how they're doing it. That's true, they're not fair. And I thought maybe that's what it meant, they're robbing from them their money. And again, that probably is part of it. But if you read Jeremiah chapter 7, you'll see that it's much worse than that. Because in Jeremiah chapter seven, Jeremiah, in a very similar way, has found a temple where the people of God, they go out during the day, and they serve other gods, and they even sacrifice to their children. They're burning their children to other gods. And they come back before the Lord in the temple, they congregate, and they say, it's the temple of the Lord, the temple of the Lord, the temple of the Lord. I don't know if that's a hymn, but certainly they're pointing to the outside works. They say we go out and we do evil, and we come back, and God has redeemed us, he saved us. Look, we're here in the temple. I think that when he says the den of robbers, it's more focusing to a wicked gathering of people where they have decided to come live. This is where the filth has gathered, in the temple of the Lord. And if we compare that to the purpose of the temple, when I said Solomon was saying and repeating over and over again, Hear us and forgive, hear us and forgive. These men were saying, this is the temple of the Lord. They're talking about the outward aspects of the temple when it needs to be an inner heart. How far from God they had fallen. I think you can see that as well. Because they had no fear for him. In verse 18, the chief priests and the teachers of the law heard this. and began looking for a way to kill him, for they feared him, yes, but why? Because the whole crowd was amazed at his teaching. There was an illustration that went through my mind as I was reading this and preparing this exhortation, a picture of a group of scavengers going through the forest looking for food, and they come upon a den, and in that den there's bones scattered everywhere, and there's fresh kilt. Clearly it's a lion's den. And they decide, hey, let's sit here and let's eat this. Why would we keep scavenging? Here's our meal. So they sit down, they eat it. And one of them gets the bright idea, why don't we just stay here for the night? Let's just sleep here. And they do. And in the middle of the night, the lion comes back. And they're standing in front of the lion. And you can think about Daniel as well, when the accusers of Daniel were thrown into the lion's den. And there's a picture of the lions jumping and leaping and crushing their bones before they hit the ground. That's the picture we have here. The lion is standing before them, but they don't fear the lion. Isn't that amazing? They fear the people, losing the people, because these shepherds have been eating from the sheep. There's a parable just after this where Christ talks about the vineyard, and when he sends his son to the vineyard to go collect the fruit, what do they want? They want to kill the son for his inheritance. They believe that the inheritance of the son, which is the people of God, is theirs. And they've been eating from them this whole time. But he's back. He says, it's my house. He's back to take it and he's bound the strong man. And that's what they fear. They fear that they're losing the people. And again, I have to bring this before you, but in John, in the triumphal entry, Greeks come up and they say, show us Jesus. Where is Jesus? Even the Greeks. And the Jews say, we're losing the whole world. The whole world is going after him. You can hear the panic in their voice. They didn't fear God, even after seeing the cleansing of the temple and after hearing the judgment given, they did not fear. But if we read in 19 through 21, the judgment of God is sure. When evening came, they went out of the city. In the morning, as they went along, they saw the fig tree withered from the roots. Peter remembered and said, Jesus, Rabbi, look, the fig tree you cursed has withered. And that is ultimately what happens with Israel. As a nation, they reject Christ. So now in the means of application, we have to ask ourselves, how can we avoid the same fate? How can we bring forth fruits of repentance that aren't leaves, but true fruit? Again, I asked, is it emotions, is it doctrine, is it habits, is it reading scripture? Those things are all very, very important for us. But those things in themselves will become leaves. No, Jesus tells us in verse 22, this is the answer, have faith in God. It has to be a work of God. And if we feel, if we read the doctrine of God, if we're reading scripture, it has to be a work of God in us to make those things meaningful. And just quickly, the next section, 23 through 25, about prayer, I'm not gonna go in detail there, Perhaps it won't be surprising to you that this is a verse that is oftentimes misinterpreted People in the health and wealth gospel say, if you pray, if you really believe, you can pray and anything will come true. It's really ridiculous. We don't need to spend any time on that. But isn't it also ridiculous that Israel thought that the blood of a bird could satisfy God? That that's what God wanted? That they could hate him? That they could reject Christ and they could offer an animal? Slay the blood of the animal? Isn't that ridiculous? And for us as well. If we believe that prayers at certain times of the day, or if we believe that being sad when we're confessing our sins, or tears, if we believe that those things in and of themselves can atone for what we have done and how we've rejected the Lord, that is ridiculous. So what is God saying here in these verses when he says, believe in God? And he talks about the power of God. He's saying look to God, don't look at yourself. Even a mountain can be turned over and tossed into the sea. It's the work of God and only the work of God that can bring fruit in our lives. And only God can turn our heart. But there had to be payment. It's interesting because for us in order to believe, there had to be payment for sins, that is Christ's blood. But when Christ was on the cross, the Pharisees and leaders of the Jews said to him, they mocked him and they said, You said you could save others. Can't you save yourself? He can't even save himself. But if he comes down from that cross, then we'll believe. If he comes down from the cross, then we'll believe. Isn't that so backwards? If he came down from the cross, none of us could believe because that was the act. When we pray, there has to be blood, and there is in Christ, his one sacrifice. When we pray, a heart changed and blood and payment that is from Christ. It is all the work of God alone. So what can we do? We must cling. We must cling to him. And just in conclusion, I wanna read this from John 15, if you'd like to turn with me there. It's page 1676. It's a passage we're all very familiar with. John 15, 1676. So vine and the branches. I just want to read the first eight verses here, and if you see the connectedness to our passage today, how do we bear fruit's repentance? John 15, I am the true vine. My father is the gardener. He cuts off every branch in me that bears no fruit. While every branch that does bear fruit, he prunes so that it will be even more fruitful. You are already clean because of the word I have spoken to you. Remain in me and I will remain in you. No branch can bear fruit by itself. It must remain in the vine. Neither can you bear fruit unless you remain in me. I am the vine, you are the branches. If a man remains in me and I in him, he will bear much fruit. Apart from me, you can do nothing. If anyone does not remain in me, he is like a branch that is thrown away and withers. Such branches are picked up, thrown into the fire, and burned. If you remain in me, and my words remain in you, ask whatever you wish, and it will be given you. This is to my Father's glory, that you bear much fruit, showing yourselves to be my disciples. Yes, we must cling to him. We must find our all in him. It's fruitful. It's joyful, excuse me, it's joyful to be able to bear fruit of repentance. Oftentimes we can think about it as something that we have to do, or something very somber, and it is. But isn't it amazing that God, He enjoys the fruit. He looks forward to the fruit. We see that Christ is hungry. He's looking into the branches for fruit. It's a glorious thing to know that the Lord is waiting for us to come to Him in repentance, in His Son, and He can enjoy that. And when we're united to Christ as our vine, then our repentance can bring forth true sorrow. Then we can have joy in reading his scripture. And more than anything, we can have renewed life in him. Amen. Let's pray. Father, our God, we thank you for your word. We thank you for the reminder, Lord, that we must have our all in you. We pray that you would teach us what it means to have true repentance in Christ, that you would help us to see and to fight against any leaves that we would put out, but that we would rely totally and only in Christ's sacrifice, that you would, by your Spirit, give us a changed heart and a heart that is true sorrow for our sins. We pray this in Christ's name, amen. If you're able, please rise. And bring your hymnal with you. We're gonna sing number 95, Gracious God, My Heart Renew, but just after that, I'll pray for the benediction. And we're gonna sing doxology number 493, Praise God, From Whom All Blessings Flow. So first, number 95, and then we'll do the doxology.
