What? We fight with spirits not humans. The NSA or CIA is nothing compared to the spiritual side. And servants of the LORD have power over it.
Everything is based in spiritual ideals. But, there is a balance. Consider King David in the OT. He was twice called by God, "a man after my own heart" (1 Sam 13:14; Acts 13:22). Yet David was one of the bloodiest of all killing machines at times.
God doesn't always destroy evil instantly. He allows evil so that evil-doers have a chance to repent. It's His way, the way of love. But He DOES destroy evil that will not repent after a sufficient time.
This is part of the spirit and the Spirit.
