There is a shift in the battle cry. Wars are not won with chariots and horses but on the altar of prayer. The posture of a true soldier of God is found on his or her knees.
There is no greater weapon in the life of a believer than to humble yourself before the living God, with sincere tears and utterance. It can literally change the world!
Corinthians 10:4-6
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.
