Saint Paul sets a muddy dirt road before the eyes of the church, a road where rain makes a mess and trucks cut deep ruts into the ground. The rut becomes the picture of sin, not just an inconvenience, but a deep and terrible track where man gets stuck and cannot pull himself free. Sin is not treated as a small habit or a bad patch in life. Sin is the old master, the tyranny under which every person is born, and no meditation, self-discipline, internal reflection, or human machination can break that lordship.
Christ has freed the baptized from that rut. Holy Baptism joins sinners to Jesus’ death and resurrection, so that those once under sin are “brought from death to life.” Sin, that wicked master, is drowned in the watery grave of baptism. Christ claims the baptized as his own, and by faith he becomes the loving and gracious master in place of sin.
Saint Paul then presses the claim of Christ all the way down into the body. The members of the body once served sin freely. Hands stole and harmed. Feet carried sinners where they ought not go. Minds schemed against the neighbor. Tongues slandered, degraded, and wasted speech. Even the less presentable parts served unchastity. But Christ now claims the body for righteousness, so that the same members are put into a new service.
The Spirit of God works in the baptized to resist sin, even while sin still resides and seeks to rule again. Hands become instruments of generosity. Feet carry the faithful to worship and to the neighbor’s need. Minds consider the good and rejoice in the neighbor. Tongues praise God and build up the neighbor, especially with the gospel. Chastity receives being made male or female with thanksgiving.
Saint Paul sets two masters and two ends before the church: sin leads to death, and God’s free gift is eternal life in Christ Jesus the Lord. Sin brings spiritual death, eternal condemnation, physical death, and temporal destruction in relationships, property, trust, and bodies. God’s gift brings reconciliation with the Father, resurrection on the last day, and even now life for the members of the body. Through righteous deeds, the Spirit brings life into marriages, congregations, friendships, and the world. The road still has ruts, but Christ and his gracious Spirit keep God’s people on the path that leads to eternal life.

Key Takeaways
- 1. Sin is the deepest rut [29:12] Sin is not merely a pattern that needs adjusting or a weakness that needs managing. Sin is the old master that holds fallen man in a rut too deep for human strength to climb out of. The frightening thing about sin is not only that it feels familiar, but that it rules while pretending to be freedom. [29:12]
- 2. Baptism drowns the old master [31:21] Holy Baptism is not a bare symbol standing outside the battle with sin. God joins the baptized to the death and resurrection of Jesus, and sin’s tyranny is broken in that watery grave. Christ does not simply improve the old life, but claims the sinner as his own and brings the dead to life. [31:21]
- 3. Bodies belong to Christ’s service [32:07] Saint Paul’s call reaches beyond thoughts and intentions into hands, feet, minds, tongues, and even the less presentable parts. Righteousness is not an idea floating above ordinary life. Christ claims the whole person, so that the body once used for harm becomes an instrument for mercy, worship, chastity, and love. [32:07]
- 4. Sin still seeks to reign [33:36] The baptized are freed from sin’s dominion, but sin still resides and tries to rule again. The Christian life therefore is not denial of remaining corruption, but resistance by the Spirit of God. Grace does not make sin harmless, but it does make sin no longer the rightful master. [33:36]
- 5. God’s gift brings life now [37:10] Eternal life is not only a future promise, though it surely includes resurrection on the last day. God’s gift already enlivens the members of the body for good works that bring life into homes, friendships, congregations, and neighborhoods. Where sin destroys trust and relationships, the Spirit works through righteousness to build up and restore.
