Paul concludes his letter to the Galatians with a warning about the persecution they will face from those attempting to distort the true gospel. He urges them to boast only in the cross of the Lord Jesus, for through it, believers have been crucified to the world, and the world to them. Paul's final words remind the Galatians that their identity and hope rest solely in the transformative power of Christ’s sacrifice, not in outward rituals or worldly approval.
