2 Corinthians 10:3-6

For walking in flesh, we do not war according to flesh. For the arms of our warfare are not fleshly, but powerful according to God to the overthrow of strongholds; overthrowing reasonings and every high thing that lifts itself up against the knowledge of God, and leading captive every thought into the obedience of the Christ; and having in readiness to avenge all disobedience when your obedience shall have been fulfilled.
