When Jesus Christ comes into your life, he becomes the sole occupant. Yet some people have suggested that Christians can be demon-possessed. However, Jesus is not in a timeshare program with your heart. The Bible says, "What harmony can there be between Christ and the devil? How can a believer be a partner with an unbeliever? And what union can there be between God's temple and idols? For we are the temple of the living God" (2 Corinthians 6:15–16).
Yet the devil would love you to think that you are powerless against his attacks, that you have no recourse, that you are no match. He would love you to believe that you will always be a victim, an addict, a puppet for him to control. And I want to tell you that is 100 percent wrong. Though it is true that a believer can be hassled or tempted or oppressed by the devil and his minions, he cannot control us.
If we yield to his power, he will have his sway in our lives. But if we resist him, we can be free from it. And here is what you need to remember: God is greater than Satan. As the Bible says, "But you belong to God, my dear children. You have already won a victory over those people, because the Spirit who lives in you is greater than the spirit who lives in the world" (1 John 4:4).
You cannot cast out temptation. You cannot cast out things that attack you. Instead, you need to deny and resist them. You need to put your spiritual armor on. The Bible says, "So humble yourselves before God. Resist the devil, and he will flee from you" (James 4:7). The key is to stay as close to God as you possibly can.
