“My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.”
1 John 2:1

The goal is to avoid sin. It’s good to have a target, so we don’t meander aimlessly. When we miss the target, we are not alone, we have a steadfast advocate. He is devoted to getting involved and getting us back on a righteous track.
Advocate: from Greek for intercessor or consoler.
