Is demon possession real?
No.
We are up against rulers and authorities in the heavenly realms and they operate “in” the world system. Bodily possession ended when Jesus Christ was raised from the dead. It was allowed to show his glorious power to deliver men while on earth. We are now to be “transformed by the renewing of [our] minds”. The battle against the demonic is with SPIRITUAL weapons, and the taking captive of THOUGHTS that exalt themselves against the knowledge of God. Believing the good news of Jesus Christ breaks demonic power. The charismatics and their demonism have wreaked havoc among many. Satan is not in charge, people. He’s on a leash and does what He is ALLOWED to do, and by God’s order.
There is no yin-yang. God is enthroned in heaven, laughing at his foes (Psalm 2) until the Day he throws Death and Hades into the Lake of Fire!
A good place to start “exorcising” Satan, then, is STOP FILLING OUR MINDS WITH HIS GARBAGE (music, movies, tv, books, sports, etc.) and filling our minds with God’s awesome Word. Get an audio Bible you like and listen to it as you walk, ride a bike, work (i had a job loading a trailer for hours and I took in a lot of His word then, and had a big smile on my face...and some tears).
If you are inChrist, I agree with you.
For the unbeliever, all bets are off.
