I'm an agnostic and got sober with AA. Still in AA 4 years later and find it beneficial. I think the most important thing for me was finding my AA "crowd" and a sponsor I could connect with. I also relied on a therapist.
Some meetings I've been to are better than others in different ways, esp WRT how hardcore religiosity can be.
One book I have found helpful in AA is ("Staying Sober Without God: The Practical 12 Steps to Long-Term Recovery from Alcoholism and Addictions)[https://www.amazon.com/Staying-Sober-Without-God-Alcoholism-ebook/dp/B07MBVCS29].
I also enjoy Russell Brand's Books, but they're not for everyone.
I too have struggled with the god concept but have finally through reading a lot of literature have found something that works for me. Read Staying Sober Without God by Jefferey Munn it gave me a new perspective https://www.amazon.com/Staying-Sober-Without-God-Alcoholism-ebook/dp/B07MBVCS29
A staunch agnostic, 14+ years sober, well and truly recovered (I hope!), I still cringe a bit when reading or hearing what I perceive of as fawning, almost drooling, holy roller exclamations of love for and fealty toward GOD.
But some of the things I've taken on in the recovery process are (I hope!) open mindedness and tolerance toward religion and religious people. I think that has real value. "Be quick to see where religious people are right." - page 87.
I also find that at the very least, a conception of god is an invaluable tool in recovery and in day to day life.
One little tip I've shared that some have found useful: I've never needed to pin down any precise or definite conception of a god or gods in order to make progress in recovery; simply acknowledging that I am not God, and that some sort of higher power could help with recovery seems to have done the trick. (And my conceptions in this matter vary, mutate, and perhaps evolve continuously.)
https://www.amazon.com/Staying-Sober-Without-God-Alcoholism-ebook/dp/B07MBVCS29 - looks like it could be an interesting book, I'll put it on my list - thanks!
My sponsor and I read books to each other most weeks during our weekly meeting, and so far it's mostly been general service approved, but we're running low on that, so we're kind of thinking one of Sandy Beach's books next, or perhaps the dreaded service manual (lol - I just remember checking it out once in early recovery, my then sponsor and I agreeing "Way, way boring!")
There is also a list of potentially helpful books here: https://aaagnostica.org/literature-3/
Thanks for sharing. Sorry if I pontificated too much above :)
