Mostly funny, yeah. But I don't think this is funny:
There were clots and the doctor's advice was, "We have to cut him open immediately to even try to save his life." Pastor Slack and those with him said, 'No, we'll pray." And they prayed... they took another set of pictures of my heart and the clots and blockages had disappeared!!! They did not cut me open.
I hope nobody follows this pastor's example in an emergency situation. If you want to pray, pray in the waiting room and don't interfere.
In light of all the obvious dishonesty, it's fairly natural, I would say, to have difficulty with the story.
