2 Corinthians 10:3-7

For though we walk in the flesh, we are not waging war according to the flesh. For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ, being ready to punish every disobedience, when your obedience is complete. Look at what is before your eyes. If anyone is confident that he is Christ’s, let him remind himself that just as he is Christ’s, so also are we.
