2 Corinthians 10:2-4

2I 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. 3For though we live in the world, we do not wage war as the world does. 4The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.
