Hello CG86. I am on my underwater laptop typing with my giant fingers as I wait for Mothra to call. But, I have a few to answer the question you posed.
If a person does not want to believe, no matter what you say, they'll blow it off as a merely subjective experience. However, I can tell you that after offering God a little more of myself on a night in June of 2012, He took away a big chunk of a lustful problem I was having. Instantly, a habit was broken. When I say "broken", I mean vaporized. Gone. Completely non-existent. Literally overnight, if not right then and there when I prayed. This habit was something I couldn't resist, not without feeling tremendous, almost obsessive anxiety. It had a nasty, relentless hold on me. I think something demonic was removed that night, and it was AWESOME.
