As Christians, we don't need to fear any of the devil's works. We have no reason to fear. James 4:7 says, . . . resist the devil and he will flee from you. . . .not walk or crawl but flee! He flees because he is the one who is afraid.
If the devil is afraid of the true child of God, we don't need to be afraid of him. God's children do not have any reason to fear the devil's power. We need to be set free and set others free by God's great power.
