Galatians 2:17-18

AUV(i) 17 But, if while we were trying to be made right with God through a relationship with Christ, we were discovered to still be sinners [by acting like unsaved Gentiles], does that mean Christ is responsible for our sin? Of course not. 18 For if I try to build up again what I had already destroyed [i.e., by returning to depend on compliance with the law of Moses to become right with God, after having rejected this system by trusting in Christ to save me], I would certainly be guilty of sin.
