You should respond positively and with great excitement when an asshole attempts to pray for and heal you. But, tell him that you’ve already accepted Jesus into your heart and God speaks to you regularly.
If you sell this story convincingly, it will no doubt pique the asshole’s curiosity and he’ll grill you on what God said to you.
Be coy and make him prod it out of you. Maybe your conversation can go something like this:
*…well, I shouldn’t be telling you this, but, uh, he conjured up a vision of you to me recently. He knows all about you. He told me you would be visiting me soon, and here you are! Hallelujah!
…he told me other things, too.*
Asshole: What did he say???
*…well, don’t take it personally, but God doesn’t like you very much. In fact, he called you a ‘dick’. That’s the exact word he used to describe you. I was quite shocked God used that kind of language, actually, but there you have it. I think you’re A-OK, but God thinks you’re a big, fat dick. Sorry.
…oh, that wasn’t all he had to say about you. Lemme tell you, when God gets wound up, he’s a regular motor-mouth. He said the main reason he doesn’t like you is because you have frequent ungodly, deviant sexual fantasies…and you masturbate far too much. He’s taken quite an interest in watching while you, as he puts it, “wax your carrot.”
God said he’s going to smite you big time for all that dirty business you engage in. He mentioned something about having your willy pull off in your hand the next time you yank on it.
Hell, I’m blind, but even I can see you’re in some fire and brimstone type trouble, buddy.
So, I asked God if there was any way you could atone for you sins and save your willy. He said he may reconsider if you flagellate yourself with a cat-o-nine tales for a week, say three Hail Marys and give me a large sum of money. Apparently, God likes me and wants me to be rich. *
