the devil has been licked

"Sir Devil," [the Christian] may say, "I am not afraid of you. I have a Friend whose name is Jesus Christ, in whom I believe. He has abolished the Law, condemned sin, vanquished death, and destroyed hell for me. He is bigger than you, Satan. He has licked you, and holds you down. You cannot hurt me." This is the faith that overcomes the devil.
