I think the 12 and 12 talks about it pretty well...
Willingness is the key. Use it to open the door. The door may close again, but next time you open that door, it opens wider and more readily. You just have to try and try.
I let go when I couldn't comprehend what it was that my life was going to be like... or if I got agitated trying to think my way through my life, especially my life in sobriety. It was too much for me... So I just trust that God must have a plan, so I need to get out of the lead, get behind Him and ask Him "How can I help you?" "What's the next right thing that I must do?"... like one day at a time, the next right thing and only that thing, then the next.
Hey, ya know... This thing, life... recovery, health, relationships... it's all bigger than me... I'm powerless, yes... not helpless... I just have to ask for Him it, and then be quiet and listen, closely.
Mark
