Avoiding God as a subject leaves one with very little else to talk about. In fact, with nothing else to talk about.
I find that I have many things to talk about other than God. Such as anime. Now, God is interesting too, but it's been so long since the last instalment of the Bible came out. Oh, sure, there's some sequels but they all take place in different timelines and I can't make out what's canon anymore. The fanfic is pretty fun though. I think a Dragon Ball-Bible crossover fic could be interesting: Goku vs. Yahweh!
Chesterton was able to write with authority about profound ideas, to write with an insider’s understanding of mysticism because he clearly passed through that moment when there was nothing but God.
If this is an accurate and fair summary of his ideas, they don't seem particularly profound to me.
