In the name of Jesus every believer becomes lord and master of all principalities, powers, rulers of the darkness of this world, and wicked spirits in heavenly places (Ephesians 6:12). They must bow to the Name of Jesus in us because He dwells in us, and we in Him (Luke 10:19, John 17:23, Romans 14:11). Besides, our Father is the Judge who said it is so (Psalm 9:8, Hebrews 1:8).
His Name belongs to us. We have been given the power of attorney to use it against all the power of the enemy (Mark 16:17, Luke 10:17, John 14:13, John 16:23). Jesus told believers to go into all the world and use His Name to cast out devils, speak with new tongues, and lay hands on the sick and they would recover (Mark 16:18).
