AUV(i)
4 For the weapons of our warfare are not like the world’s [i.e., which rely on human ingenuity and unspiritual principles], but they are empowered by God to overthrow [Satanic] fortifications.
5 We overthrow [vain] reasonings and every lofty idea raised against the knowledge of God [i.e., as revealed through the Gospel], and take captive [our] every thought to [make it] obey Christ.
6 [And we are] prepared to punish all disobedience when your obedience is complete. [Note: This probably refers to the Corinthian church dealing with its unrepentant member. See I Cor. 5:3-5].
