But I presume that people sincerely get their spirituality from the Bible and the life of Jesus, so it’s not all useless and wacky
Wisdom/spirituality in the bible is like corn in a cow patty.
Sure you can find some whole (undigested) kernels (of wisdom) in there. But is it really worth the trouble to dig them out, when you can find good kernels anywhere. The BS negates whatever good. Just throw it out and start fresh. There is no unique good stuff in the bible.
