The Burden of The Mediator

How do we see that Christ is the only Perfect Mediator? Why were the fleshly types of Christ such failures? Why did Moses complain about his role as mediator for the LORD’s people? Why did Moses ask for the LORD to kill him in his feebleness? What is the comparison between Christ and Moses? How does the weaknesses of the types of Christ show forth the glory of God in Christ? Why did the LORD choose to make Moses fail? What was the purpose of Moses as a type of Christ the Mediator if he was going to fail? What was the true purpose of the law? How great a weight was it for Christ the Just to bear the sins for the unjust?
