My youth pastor has actually spoken about his experiences with praying over homo/trans/bi -sexuals and “freeing” them of their demons.
Your pastor is a charlatan.
I don’t remember if he used the terminology I did here (and I think I did a pour job of saying that, now that I think of it), but how can you claim he has never seen a person with a “different” sexual preference change their mindset after prayer? Believe me, I know this man, he is no fraud. He claims nothing of himself that is fraudulent.
Because sexual preference isn’t something you decide. A homosexual might start “doing it” with people of opposite gender, but he won’t enjoy it.
It’s like eating peanuts when you’re allergic to peanuts.
