There is great reward in keeping the law of the Lord. Keep me from sin and forgive me. I have been forgiven much. Let my sin not rule over me. (Psalm 19)
You don’t have to react. You are free in Christ. You are free from bondage. You are free from having to do anything except God’s will. It’s a lie that you can’t help it, that you can’t change. His grace is sufficient, not lacking in any way.
