I'm not remotely Christian but as I get older and the more I'm able to analyze and interpret fantasy and mysteries, I'm finding I'm able to understand what the Bible is going for.
Like it's easy for a kid to poke holes in the book, but when you give it the benefit of the doubt, and you start trying to see the author's intent, I appreciate the overall message.

It was a fantastic civilizational ordinance for establishing public order, common decency and creating high trust environments. It established itself in the most advanced civilization on earth for a reason.
Compared to its competitors in Confucian or Tao, or Islamic, or Vedic texts and you realize we got lucky. Either a philosophy is too strict or hierarchical and while a society continues it doesn't advance. Christian philosophy was a cocoon that allowed for western society to progress til the point it wasn't needed anymore and now we've shed to husk and now now religion is needed. Meanwhile the middle east has modern technology and cannot escape the cocoon of islam. I think thanking Christian history is the least we can do.
