Resist the Devil and he will flee for his life is a verse that is rarely translated with the power and authority that Jacob put there.

Jacob 4:7. Therefore if you would be subject to God, you should resist the devil and he will flee for his life from you, 8. draw near to God and He will draw near to you. Cleanse your hands, you sinners, and purify your hearts, you doubleminded! 9. You must now feel afflicted and miserable and weep and cry! Let your laughter turn into grief and joy into dejection! 10. If you would humble yourselves before the Lord, then He will lift you up.
