To work steps 2 & 3, one *must* have some concept of a Higher Power. The chapter "We Agnostics" speaks specifically to those having difficulties with grasping the concept. I think you are reading things into it that aren't there.
One good explanation I heard on a speaker recording suggested that someone simply envision a Higher Power that is exactly as they wished it to be.....end of exercise! For me, the key point was that, whatever that Power is, it is NOT me. Its not a complicated concept, unless we choose to make it so!
