I know what you mean. JP's biblical lectures were the first thing that made the concept of "God" as a framework for conduct and interacting with the world into something that was accessible to someone that doesn't believe in fairy tales.

I wouldn't call myself a Christian – I'm athiest, or at least uninterested in prioritizing any diety concept above any other – but being able to finally "get" what (some) religious people see in their texts was awesome.

The biggest help was basically learning to steelman the texts. Rather than viewing them as default stupid and looking for chinks in the armor, viewing them as containing something abstract but useful that I didn't understand and attempting to meditate on what that might be and why it might work has been valuable.
