From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of [from] the elders and chief priests and scribes [experts in the law WU], and be killed, and be raised again the third day. Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be [done] unto thee. But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence [stumbling block] unto me: for thou savourest [have in mind WU] not the things that be of God, but those that be of men. Mat 16:21-23 Satan is a stumbling block to the righteous and uses other people, sometimes other believers, to try to pull our hearts away from God. Jesus verbalized what was happening and confronted it forcefully. (Click gold Scripture references for Principle Interrelations)

When the unclean [an evil WU] spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none. Then he saith, I will return into my [the WU] house from whence [which] I came out; and when he is come, he findeth it empty, swept, and garnished [put in order]. Then goeth he, 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 also unto this wicked generation. Mat 12:43-45
