I mean the framing of an abstract non-entity God is a stretch from how basically everyone actually invokes God. Sure, that conception of God has been around a long time - however I've yet to come across any religion that sticks to that conception. Instead it's generally used as part of a Motte and Bailey setup - such an abstract conception of God cannot be disproved, and so one has to agree that such a God may exist. But then having established that, the general feeling that there is some kind of higher power is used to give weight to a whole bunch of assertions of what a completely different conception of a higher power supposedly wants us to do.
Maybe in some circles, but the abstract idea of God being love (assuming one has faith that consciousness and free will exists in reality) go back millennia. The abstractions predate the Simpson’s ‘beard in the sky’ by a few years ;)
