It is the devils that want us to suicide. That way they can keep those souls. I have had to deal with porn and masturbation. It was after watching some of those Youtube videos that talked about seeing hell and them that did fornication and masturbation that got me to finally stop. If you can just lust in your heart and be guilty of fornication, then how can someone masturbate and not think of lust after even an unknown partner? To me it seems we must learn to bind evils spirits in the name of Jesus and loose spirits of God in the name of Jesus. It would help in the struggles of all believers.
