Won't Be Long Now!
While the Holy Spirit can surely help a Christian to refrain from sin or watching ungodly things, in my humble opinion the Holy Spirit does not stop you from ones sinful ways. I base my conclusion on many verses, but here are some that kind of make that point. Paul is making the point that a fornicating Christian is sinning against their own body where the Holy Spirit is residing. So he is extorting saved Christian, not to do that.There is no actual connection. A person can certainly watch horror movies and still be saved.
And yet, I cannot help but conclude that the indwelling presence of the Holy Spirit within a truly saved individual would naturally cause him or her to become highly repulsed by gory images of evil and death.
1 Corinthians 6:18 Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.
1 Corinthians 6:19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
1 Corinthians6:20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
