"God may or may not exist. If there is such a thing what can anyone do about it?" I'm not sure I understand your question, what to 'do' about what?

As to "whether any particular religion has an acceptable answer", no 'religion' whatever one's definition can replace a personal 'relationship' with one's maker. not even my opinions which you're reading. only a person's heart knows their questions, and bringing them out in the open with the maker who matters is the way to a personal relationsip, just like speaking with one's spouse far surpasses reading guidebooks on communicating with another. sometimes it is taught to 'fear' God. well, yeah, cuz he's bigger than death. but no where does it say to fear trying to speak with him. and he doesn't say to see everything as sweetness and light, he says 'be angry but don't sin, like don't let things allow you to choose to become that which grives you.

i've been brutally honest vocally with Him during certain adversities, 'I AM FAILING TO UNDERSTAND WHAT'S EXPECTED OF ME HERE!!! YOU'RE GONNA HAVE TO HELP ME!". he's always attentive even when i'm not, so i find that helpful.
