In this week’s teaching, we examine Chapter 2 of Devoted to God, titled “All of Me.” Sinclair Ferguson unfolds the gospel logic of sanctification through Romans 12:1–2.

Sanctification, Ferguson argues, is not rooted in personal discipline or moral effort, but in the mercies of God. God has acted in Christ, and we are joined to Christ. God’s saving work always precedes our response. His grace is the power that leads to our growth in holiness.

The chapter highlights four foundational principles.

First, sanctification flows from the gospel, guarding us from a performance-based spirituality that mirrors the errors of the Pharisees.

Second, sanctification is embodied—our holiness is expressed through what we do with our bodies, offered daily as living sacrifices to God.

Third, sanctification requires the renewal of the mind, as Scripture reshapes our thinking and desires in an ongoing, Spirit-driven process.

Finally, sanctification reveals the goodness of God’s will, transforming our perception of obedience from burden to joy as we are conformed to the image of Christ.

This gospel-centered vision reminds us that sanctification is the work of the Triune God. The three persons, Father, Son, and Holy Spirit, continue to shape believers for glory. As God works in us by His Spirit and through His means he is teaching us what it truly means to be devoted to God with our whole selves.
