A lot of us don't. I saw his retard son claim that Trump "Saved God," which is, frankly, the most offensive thing anyone of note has said, ever, full stop.
You have to remember that the majority of the hyper evangelical fuckwits that glaze Trump are basically violent turbo pagans that ramble in tongues and charm snakes. Their connection to Christ is tenuous at best and often their teachings align directly against what Christ and the Word of God tells us.
As an aside, I do think it's fascinating that he's become seemingly obsessed with the afterlife and being "good enough" to get into Heaven. It's really strange. How he acts is not how someone secure in their faith acts. He is acting like a disgusting rich faggot close to death who just had someone point out that the deck is stacked against rich people getting into Heaven. He's a scumbag, a grifter, and the worst thing to happen to American Christianity since Mormonism.
