The sermon opens in Matthew 3:13-17, the account of Jesus' baptism by John the Baptist at the Jordan. The preacher briefly recaps John's ministry: after roughly 450 years of prophetic silence, John arrives calling Israel to repent because the kingdom of God is at hand. His baptism is a sign of purification, but he insists it is preparatory, not final — one greater than he is coming, who will baptize with the Holy Spirit and fire, calling and enabling genuine repentance rather than merely announcing it.

Into this scene steps Jesus, traveling roughly sixty kilometers from Galilee to Jordan to be baptized by John. The sermon dwells on the strangeness of this request. John's baptism signified repentance from sin, yet Jesus is sinless; John himself protests that he is unworthy to baptize Jesus and instead needs to be baptized by him. Jesus' answer in verse 15 — "let it be so now, for thus it is fitting for us to fulfill all righteousness" — becomes the sermon's central question: what righteousness is being fulfilled, and how does submitting to a baptism of repentance accomplish it?

The sermon argues that by receiving baptism, Jesus identifies himself with sinners who need repentance, acting as the representative of God's people — a king submitting to the prophet's call on behalf of a nation that must repent, even though he himself is innocent. This, the sermon explains, fulfills what is said of the suffering servant: the Messiah bears the sins of many. Yet the sermon pushes past mere representation into the richer category of union with Christ, describing a togetherness so intimate that in it Christ takes up the guilt of his people's sin as his own.

To unpack this, the sermon reframes water baptism as fundamentally a symbol of God's judgment, not primarily purification. It traces this through the Old Testament, especially Israel's crossing of the Red Sea, which 1 Corinthians 10:1-2 explicitly calls a baptism: the Israelites pass through the water unharmed while Pharaoh's army is engulfed. Romans 6:4 links Christian baptism to burial with Christ, and the sermon presses the question of why the Israelites, no less sinful than the Egyptians, escaped judgment. The answer is substitution: judgment fell instead on the Messiah foretold by Isaiah, who would bear the people's sin and be crushed in their place so that they might have peace with God.

This substitutionary logic gives Jesus' own baptism its unique, even tragic, meaning. Whereas everyone else who is baptized passes through the water of judgment unharmed because judgment has been transferred onto the Lamb of God, when Jesus himself enters the water, the judgment is not transferred away — he bears it fully, and the water anticipates his actual death. His rising from the water anticipates his actual resurrection, echoing the sign of Jonah. The sermon connects the descending dove to Noah's flood narrative, where a dove returning with an olive branch signaled the end of judgment and a re-created world, and further back to the Spirit hovering over the waters at creation. Drawing on 1 Peter 3:20-21, the sermon presents Noah's ark as a type of Christ: those hidden in the ark are carried safely through the water of judgment, just as those found in Christ pass safely through God's judgment because he bore it in their place.

The sermon then confronts a common objection: is it not unrighteous for God to simply forgive sin without punishment? It argues that this objection rests on a self-serving, relativized standard of righteousness — one that excuses "smaller" sins as harmless or universal while reserving condemnation for society's worst offenders. Only God's own standard, not any human or cultural standard, has the right to define sin and righteousness, and by that standard all have sinned and deserved judgment. If God's righteousness were to be fulfilled by human effort or mere confession, no one could have survived Eden, the flood, or the Red Sea. The unrighteousness in forgiveness is resolved only because payment has been made — Jesus came not to escape judgment but to die under it, so that the demands of righteousness are fully satisfied.

The sermon closes on the Father's declaration, "This is my beloved Son, with whom I am well pleased," reading it against the echo of God's call to Abraham to offer his own beloved son — except here God does not stay his hand. This is framed as the deepest tragedy and glory of the gospel: the Father giving his Son to bear humiliation, wrongful accusation, and death for a people who had done nothing to deserve rescue. The sermon ends with a call to look to Jesus as the one who bears sin, guilt, and punishment on behalf of all who trust in him, inviting both non-believers and believers to receive at the Lord's table what none of them deserve but what is freely given through Christ's sacrifice.
