God's Covenant Promise

Reformed theologians commonly cite Acts 2:39 as evidence that baptism seals a covenantal promise and should also be administered to the children of believers. Others deny this, claiming that Peter is simply declaring his gracious invitation to all mankind, Jews and Gentiles. But that claim doesn't go deep enough.

Peter reminds his audience that the promise is for "everyone whom the Lord our God calls to himself." Those who receive the internal call, the effectual call will be saved, the elect. But this group is made up of two people: "you and your children" AND "all who are far off." And while the fact that salvation is offered to "all who are far off" is good news God is saying something special to mature covenant members and their children.

Baptism is like the signs that God gave to Gideon which were meant to encourage him that faith would have the victory. "Wherever … there is a word of promise confirmed with a token, never fear a disappointment."
