II Corinthians 10:3-7

For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, and being ready to punish all disobedience when your obedience is fulfilled. Do you look at things according to the outward appearance? If anyone is convinced in himself that he is Christ’s, let him again consider this in himself, that just as he is Christ’s, even so we are Christ’s.
