In the early days I was a bit lost in the God department. I refused to attend a meeting that used the Lord's Prayer, in fact I remember feeling quite irate about it. I had no experience of, and therefore no belief in God. That does not mean I was an atheist. That is a form of faith itself, a belief that there is no God, which cannot be proven either.
I listened to the "group of drunks" idea and made the group my higher power for a short time. After all they were sober. I soon learned however, that people have feet of clay. I needed something a bit more substantial.
I was at least willing to believe that the power that helped them might possibly help me, which apparently was all I needed to make a start. I pursued this idea a bit like a scientific experiment. Basically if I did exactly what they did, I ought to get what they got. I began getting results quite early, though only realised it when I was about a third of the way through the steps. I felt something that I had not felt before. That was good enough for me.
Defining what I now call God, mainly because I can't think of a better word, has been impossible for me. It feels like that "untapped inner resource" that the book talks about. I don't know if that extends to some deity in the sky. It is more like a good friend who has stood by me in the difficult times, and sent me inspiration and guidance for how I live my daily life. Communication is facilitated through prayer (talking) and meditation (listening), and the Power obtained seems to be totally portable, so I have been able to go anywhere in the world without risk of a drink. My sobriety has become independent of things human, even AA.
I dont know whether it is internal or external, but connecting and staying connected to my concept of a Higher Power has resulted not only in freedom from alcohol, but freedom from dependence on anything human.
