Paul isn't painting a poetic picture—he's confessing a radical shift: his old identity, driven by rules and self-effort, has been put to death alongside Christ's sacrifice.

In its place rises a new reality: Christ's own life pulses within him, not as a distant ideal but as an empowering presence.

This transformation mirrors the promise in Deuteronomy 33:25 — our strength comes not from ourselves, but from God's provision for each day.

Paul calls it "the secret of the exchange": trading a life bound by sin and law for one energized by Christ's haunting love.

F. B. Meyer summarizes that through this exchange, "self-control" gives way to "God's control," and the penalty we owed is wiped clean by Jesus' death.

Just as Deuteronomy promises strength for each day, Galatians reveals how that strength comes through a divine exchange — our weakness for His power.

Living "by faith in the Son of God" isn't a one-time decision but a moment-by-moment posture of dependence.

Christ's resurrection power now enables us to "live for Him in a way that pleases God," moving us from obligation to joyful reliance.

This daily dependence is the practical outworking of Deuteronomy's promise — as each day brings new challenges, His strength meets us there.
