There are no "very good Christians" no not one ,that's why we need a savior! I was led to Christ by a guy I met at an aa meeting 15 years ago! Funny thing was I asked him the same question you pose, he suggested that it only had to be higher than me (no pun) like the group,or somebody who wasn't drinking , it seems that the intention was not to force God on people, but rather introduce a concept to the recovering person ---OTHERS --- the aa writings expose the root of most of our troubles grew out of our self centered attitudes. All the steps speak to this. Jmo. We can only keep what we have by giving it away!
