Introduction to spiritual warfare

Spiritual warfare exists in the invisible supernatural level. God is omnipotent and Satan is rebellious. As any Christian will soon discover, although the spiritual war is invisible, it is absolutely true. The Bible mentions spiritual wars in many places. Most directly, in Ephesians 6: 12, Paul talks about putting on all the military uniforms given by God: "Because we are not fighting against flesh and blood, but against the ghosts and demons in power, and we are in charge of this dark world, and the sky is dizzy."
