Many of us come into sobriety very beat up by drugs and alcohol and do not believe in any kind of power or God. How could a loving and powerful God let the things that have happened to me happen? Our egos and minds tell us that there can’t be anything other than our will that will help us.
The first step to getting over this is to realize that our minds and thoughts are lies. Look around the rooms of AA/NA, and it is proof enough that the people who have made their own conception of a higher power are the people that are smiling and who have good lives.
The second step only asks us to be openminded and willing to believe that there is something other than our will power that will help us. However small that belief is OK to start. After that you are on the road to happy sobriety.
