A higher power can literally be a doorknob, the term is taken very literally. I was initially scared off for that reason, i definitely didn't want to be part of a group that shoves "God" down my throat. However, ive found that anyone that mentions Jesus or the Biblical God gets spoken to about it, most meetings generally aren't cool with that. Though I will say, they do say the lords prayer at the end of some meetings, which is a bit weird. It's not mandatory though (nothing is in AA, except a desire to stop drinking/using) and i normally don't take part.
