Using the powerful name of Jesus means "Galatians 2:20-21 KJV I am crucified with Christ: nevertheless I live; YET NOT I, BUT CHRIST liveth in me: and the life which I now live in the flesh I LIVE BY THE FAITH OF the Son of God, who loved me, and gave himself for me. [21] I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain." because our authority is now no longer and never by ourselves but by Christ alone.
