My little children, I am writing these things to you so that you will not sin. But if anyone does sin, we have an advocate before the Father—Jesus Christ, the Righteous One. He Himself is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world. — 1 John 2:1,2
The presence of an advocate transforms the experience of failure from a moment of condemnation into an invitation to return to grace, shifting focus from personal performance to the sufficiency of Christ's finished work.
