2 I beg you that when I come I may not have to be as bold as I expect to be toward some people who think that we live by the standards of this world. 3 For though we live in the world, we do not wage war as the world does. 4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. 6 And we will be ready to punish every act of disobedience, once your obedience is complete. — 2 Cor. 10:2-6 NIV
After admonishing the Corinthians for allowing impurities in their worship service and then expressing his joy because of their repentance, Paul expresses his concern that some of them still haven’t gotten the full message. They are still trying to bring the world into the church instead of carrying the church into the world. Just as with the Corinthians, our actions do not always back up our teachings. Paul starts teaching the Corinthians and us about where the problem is and how we should attack it. The problem is our mindset and that is not a battle that can be won with worldly weapons. The world and satan hits us with a constant barrage of violence, sexual innuendos, and all manners of chaos. To protect our minds, we need to fill them with the knowledge of God and be constantly filled with the Holy Spirit. Every thought that comes to our mind, must be immediately processed and either deleted or stored in our arsenal of divine weapons. We can’t dilly-dally or play games or we will be overpowered with fleshly desires. Be on the alert! Be ready to punish and cast out every vile and sinful thought.
8 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. 9 Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings. — 1 Peter 5:8, 9 NIV
