I have never believed in the old white haired bearded god figure... I think I believed in Santa Claus longer than some fearful old fart and the myths of "his" martyred son.
I
do believe in a power greater than myself and that made it easier to get passed the language of AA and get going with the program. I still rearrange the prayers and get rid of the "thous" and "thy's" just because they give me a headache and leave me empty and filled with contempt.
I believe the "take what you want and leave the rest" aspect of AA/NA to be the programs strongest appeal. The 12 Steps are an archtypal spiritual program. When I removed from my mind's eye organized religion's concept of god I was ever so able to move on and change my life for the better, inside and out.
Congrats on your getting past a major stumbling block of the program. I'm sure you will never regret it.
