Hebrews 6:1

Therefore, leaving the discussion of the elementary principles of Christ, let us go on to perfection, not laying again the foundation of repentance from dead works and of faith toward God.

The devil always wants to drag us back to our beginning and make us feel like we have to keep repenting. NO! Remind him we are a new creature in Christ, and all the old is washed away. Then move onto perfection in Christ through the word. Our faith over the past dead works is what will help us make progress.
