Satan is a looser. Believers know already that the devil is powerless over them. That's why we face life with boldness and without fear, because fear is the major instrument he uses to distract us. Fear of the future, fear of people, fear of sin, fear of the economy, every form of fear. But the Bible says Perfect love casts out fear. Fear is a torment, and a gateway to punishment by the devil.
I face life with boldness and I am unshakable because I have an anchor in Christ. Hallelujah
He is literally trying to kill us because we humans will replace him and the fallen angels. We have an unmovable anchor in Christ!
