"Submit yourselves therefore to God. Resist the devil, and he will flee from you."
The name of Jesus is what causes the enemy to flee. All temptation to sin comes from the trickster, but he has very little power. Don't give in to him, but use your authority and cast the evil one out. However, you must know Jesus and give him your heart in order to use His name, otherwise you may hear, "Jesus I know, and Paul I know, but who are you?"
