2 Corinthians 10:4-5
For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;
Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
And having a readiness to revenge all disobedience, when your obedience is fulfilled. [Dake A.R.B.].
1 – Destruction of strong holds – We destroy reasonings of pagan philosophers and Jewish rabbis and their dogmas that nullify the Word of God and the facts of the Gospel. These fortifications we pull down and demolish. We put to flight the demon powers and alien armies, raising the banner of the cross high on the field of battle. [v4]
2 – Casting down imaginations – We demolish all theories, reasonings, and any high system of ethics, religion, mythology, metaphysics, sublime doctrines, or philosophy set forth to defy the knowledge of God [v5]. All the boasted gods, lords, sacrificial and mediatorial systems fell before the Gospel. The high-sounding phrases of Plato, Aristotle, the Stoics, and even Judaism fell before the preaching of the crucified and risen Christ; Heathenism shrank before the Gospel and called on secular powers to defend it.
3 – Bringing into captivity every thought to the obedience of Christ – We take every thought prisoner and lead it into captivity to obey Christ [v5]. Lascivious, vain and evil thoughts of all kinds are brought down and made obedient to His laws. That includes any thinking which is contrary to virtue, purity and righteousness. See Mat. 15:19; Mk. 7:21-22; 1 Cor. 13:5; Gal. 5:19; Phil. 4:8; Gen. 6:5; Prov. 15:26; Isa. 55:7; Isa. 59:7; Jer. 4:14.
4 – Having in readiness to avenge all disobedience – We stand at all times ready, so to speak, to court-martial any opposing the Gospel of Christ, after separating ourselves from them [v]. The whole picture here is that of a strong fortified city where the enemy makes his last stand; entrenching himself about the walls; raising towers and preparing engines of defence and offense upon the walls to insure victory. The fortifications, walls, towers, and castles are taken by the Gospel and the whole opposition is destroyed and taken captive.
