Be self-controlled and alert. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that your brothers throughout the world are undergoing the same kind of sufferings.1 Peter 5:8-9
Satan is no play or pretend thing. He and his power are real and intended to harm. But rather than spending our time worrying about him, let's resist him when we are tempted and focus on Jesus. He's the one who won the big showdown at Calvary, triumphing over Satan. He took Satan's greatest tool and disarmed it. Jesus broke Satan's stronghold over us. Now we can resist and Satan will flee.
