Desire sits at the center of the human heart. A first grader is driven by desire, junior high is driven by desire, college is mostly still driven by desire, and adults are basically junior high with less energy and more disposable dollars. Luther’s point in the catechism lands right there: “that which you love with your heart is your god.” Desire is not a side issue. Desire is the trellis the heart grows on.
The vine image makes the problem plain. The human heart was made to cling to God and grow up in God, but sin wraps the heart around lesser supports. Security, comfort, reputation, pleasure, success, family, politics, and the self all promise life. Desire believes those promises and starts organizing everything around them. The heart lives for whatever it believes gives life.
Sin does not merely create bad behavior. Sin teaches desire to cling to the wrong things. The old Adam says, “I want what I want,” and then treats other people and good gifts as things to use, control, or consume. Money becomes more important than generosity. Comfort becomes more important than faithfulness. Approval becomes more important than truth. Even good things become idols when they occupy the place of God. Sin curves the person inward, toward self preservation and self glory, and it finally destroys the very gifts it claims to love.
Christ answers that disordered heart with a deeper security. Jesus says that not one sparrow falls apart from the Father, and even the hairs of the head are numbered. God’s care is not earned by proving worth. God loves and cares because that is who God is.
Paul then gives baptism as the foundation for rightly ordered desire. Baptism brings the person from death to life. Baptism unites the baptized to Christ’s death and resurrection. Baptism gives a new family, a new Lord, a new citizenship, a new power against sin, a new relationship to death, a new future, a new understanding of possessions, and a new purpose. Like adoption papers signed before a judge, baptism changes the future because the family has changed.
The new man and the new woman in Christ learn new loves from that foundation. The old Adam asks, “What do I want?” The baptized life asks, “What does the God who saved desire for his creation, for his people, for the neighbor?” The Spirit slowly teaches the heart to wrap around God like a vine on the right trellis. Augustine’s language fits here: sin disorders love, but Christ heals love by union with himself. Baptism begins that new ordering, and the Spirit keeps shaping desire toward life rather than sin and death.

Key Takeaways
- 1. Desire reveals the heart’s god Desire is not just an emotional impulse or a childish weakness. Desire shows what the heart believes will give life, safety, meaning, and joy. Luther’s catechism cuts through appearances by saying that whatever the heart loves most functions as god. That makes desire a spiritual diagnostic, not a small personality trait. [65:12]
- 2. Sin twists good gifts into gods Sin does not always begin by hating good things. Sin often begins by taking God’s gifts and asking them to become ultimate. Money, comfort, approval, family, and ministry can all be turned into foundations they were never meant to be. When a gift becomes a god, it stops being received with gratitude and starts being controlled with fear. [69:42]
- 3. Baptism gives a new foundation Baptism is not just a religious memory or a symbolic marker. Baptism is the place where Christ gives his death and resurrection to the baptized and brings the person from death to life. Like adoption papers signed before a judge, baptism changes family, future, identity, and security. From that foundation, desire can begin to be reordered rather than merely managed. [72:06]
- 4. Christ changes death’s meaning Death still feels frightening because death remains an enemy. Yet death is no longer the final word for the one united to Christ. Christ died and rose, and the baptized are joined to his resurrection life. That new future reshapes present fear because the end is not annihilation, but new creation. [74:56]
- 5. The Spirit teaches new loves The Christian life is not built on trying harder to become perfect by force. The Spirit teaches the baptized heart what God loves and slowly trains desire around that goodness. The vine learns to wrap around the right trellis, and the heart learns generosity, faithfulness, truth, and love of neighbor. Rightly ordered love grows from union with Christ.
