Maybe it's not about abandoning God at all, and instead merely broadening your definition of the divine so as to encapsulate and swallow it all, every God, every dogma, every attempt to corner the market on belief and parse it and put it into cute little boxes and break us all up into angry tribes who stomp our feet and wave our little gilded books and launch screaming bloody wars over promised lands and chosen peoples and crucifixes and crusades and witches and pagans and gays.
In other words, maybe you abandon God by realizing it's all God, it's all divine, all hot, thrumming, vibrating connection in all places in all things at all times. And hence, to try and parse it and restrict it and beat it into submission and claim it for one people, one history, one country or church or authoritarian body, is actually the highest form of divine insult.
Or, you know, grand cosmic joke. Same thing, really.
