A lot of folks make their higher power the group....or the principles of AA etc. All you need to get started is a belief in a power greater than yourself...or a willingness to believe there may be something greater than yourself. For me, that has changed over time but ...for me...it boils down to the Universe....the universe is infinitely more powerful than me...there are laws of nature which i will never understand and which i do believe are divinely created. The rest, I do not know. My advice - go and take what you can and leave the rest. Say the ABCs in your head if the Lord's prayer bothers you or if you have trouble listening to someone drone on and on about God. That is what I did early on. Now I just let others believe as they wish, knowing that I can do the same.
