I Peter 5:8, Be sober, be vigilant, because your adversary the devil as a roaring lion, walketh about seeking whom he may devour."

John 10:10, "The thief cometh not but for to steal and to kill and to destroy, but I am come that they might have life and that they might have it more abundantly."

Matthew 12:43-45, "When the unclean spirit is gone out of a man, he walketh through dry places seeking rest and findeth none. Then he saith, "I will return unto my house from whence I came out." And when he is come he findeth it empty , swept and garnished. Then he goeth and taketh with himself seven other spirits more wicked than himself and they enter in and dwell there. And the last state of that man is worse than the first. Even so shall it be to this wicked generation."

James 4:7, "Submit yourself therefore unto God. Resist the devil and he will flee from you."
