We think of possession as in the Exorcist, a movie about a girl whose head spins around, or of the guy who lives in tombs and scares people. There's another kind of possession that's just as real. The kind that takes place even with believers when we give the enemy a place in our lives by acting with sinful motives, or speaking words of destruction, gossip. Then the enemy can spread destruction, not only in us, but through us. We offer ourselves to be used for the enemy's purposes when we allow ourselves to be controlled by bitterness, pride, and selfishness. Peter loved God, but he allowed himself to be used by the enemy. He rebuked Messiah and told him not to go to Jerusalem. Messiah said, "Get behind me Satan." When we allow ourselves to be used by the enemy to tear down, hinder, discourage, or harm, we're allowing ourselves to be possessed for his purposes. It's not just people whose head spins around, it's when you let yourself be used. Reject the slightest hint of possession. Be moved only by the Spirit; you are God's possession.
