"The dark thoughts and violent impulses I have mean I'm demon possessed and beyond help."
How it sounds in your head: I think about hurting myself or weird violent stuff I'd never do, but what if I'm not me anymore? What if something evil is inside me controlling my brain? Normal Christians don't have these thoughts.
"He has delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love."
-- Colossians 1:13Enemy exploits puberty brain chemistry changes and intrusive thoughts (normal psychological phenomenon) to claim ownership where he has none.
Intrusive thoughts feel alien and horrifying, especially violent or sexual ones that contradict his values. The shame is so deep he can't tell anyone, confirming the lie that he's uniquely corrupted.
Man so possessed he lived naked in tombs, cut himself with stones, broke chains, and terrified entire towns. One encounter with Jesus and he was INSTANTLY 'sitting and clothed and in his right mind' - immediate total deliverance, no process required.
I REFUSE the lie that dark thoughts equal demon possession. IT IS WRITTEN that I have been DELIVERED from the power of darkness - past tense, finished work. My citizenship is in the Kingdom of light RIGHT NOW. IT IS WRITTEN that greater is He who is in me than any voice, any thought, any fear. I am sealed by the Holy Spirit. The BARAK blessing of Abraham rests on me - the same covenant protection that shielded liars and deceivers shields me. I am NOT my thoughts. I AM a son of God, seated with Christ in heavenly places.
Your Father sees a teenage boy whose brain is rewiring during puberty, producing random intrusive thoughts that mean NOTHING about your heart. He's not horrified by your thoughts - He's running toward you with the robe of righteousness, silencing every accusing voice.
