2 Corinthians 10:4-6
4  (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)

6  And having in a readiness to revenge all disobedience, when your obedience is fulfilled.

 

Romans 6:6-7
6  Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
7  For he that is dead is freed from sin.
