OMC—you nailed it! He is actually a member of Mensa, no joke. As such, you bet there’s nothing anybody can tell him.
The truth is, he’s quite smart but lacks wisdom. He had a major, major heart attack [smokes like a smokestack & drinks a lot on a daily basis]. Afterward he wrote a piece for the local paper entitled ‘Surviving a Heart Attack’. He ended with the lines, ‘My Christian friends are using the experience to try to convert me. I don’t know why; I’m not trying to convert them to Wicca’.
Sigh.
Pretty sad state of affairs. Not interested in truth, so there’s not much to work with. All you can do is pray for him.
