One reason so many people believe they need God to achieve sobriety is that they come into AA convinced they lack the inner strength to do it on their own. When they hit bottom they had begun to believe everybody who called them irresponsible losers. Which, at that point, they were, but the others were wrong when they told them they would never amount to anything and would die Skid Row bums. Bill W confirms and perpetuates this negative belief but offers them the “only” way out through their acceptance of a higher power that can help them along.
You might say, “There is always another way out,” but not everybody thinks like MacGyver. They reach sobriety sure that Jesus carried them for part of the way and cannot be convinced that, when there was a single set of footprints on the sand, it was theirs. I feel sorry for them like they feel sorry for me, but I feel especially bad knowing they might be one crisis of faith away from their world collapsing like a house of cards while I, with their support and love, can drag myself into the breach once more. After one of my more peaceful discussions I overheard someone say that he had never realized how much harder it was for atheists because we don’t have a higher power to fall back on. I wanted to tell him that he didn’t really have a higher power, either, and he had done it himself by drawing on his own resources, but if believing in God had gotten him this far I was not going to argue with apparent success. And I don’t even mind genuinely concerned people encouraging me toward God. I say, “No thank you, but I appreciate your interest.” All I ask for is respect for my own beliefs as I respect theirs with nobody calling me a savage or a vampire. Imagine the uproar if they were to call people of other minority groups such things! The day of it being open season on atheists is coming to the end, but I will try to stay polite.
