The OT storyline that I posit as the basis for the NT storyline is this: The Old Testament is the story of God, who progressively reestablishes his new-creational kingdom out of chaos over a sinful people by his word and Spirit through promise, covenant, and redemption, resulting in worldwide commission to the faithful to advance this kingdom and judgment (defeat or exile) for the unfaithful, unto his glory.
The NT transformation of the storyline of the OT that I propose is this: Jesus’s life, trials, death for sinners, and especially resurrection by the Spirit have launched the fulfillment of the eschatological already-not yet new-creational reign, bestowed by grace through faith and resulting in worldwide commission to the faithful to advance this new-creational reign and resulting in judgment for the unbelieving, unto the triune God’s glory.

I have great respect and affection for Paedobaptist Christians who argue along these lines. Some of them are my close friends or historical heroes. And the arguments [for paedobaptism] I’ve sketched above display careful attention to Scripture and reverence of Scripture. Yet I don’t think they’re persuasive. Here are six reasons why.
- Paedobaptism applies the sign of union with Christ to those who are not united to Christ. It divorces the sign from the reality.
- Paedobaptism confuses being born of Christian parents with being born again by the Spirit.
- Paedobaptism mistakenly assumes that God is forming his new covenant people the same way he formed his old covenant people.
- Paedobaptism undermines the church’s saltiness and lightness (Matt. 5:13-16).
- Paedobaptism dissolves two crucial differences between baptism and circumcision.
- Paedobaptism makes God’s new covenant promise less than a promise.
