What a great story!
I am in an outpatient program at a treatment center. They were telling the story of a young man in that treatment center that decided the other day to leave. He was going to walk home (50 miles away). He got as far as the next block to a convenience store. Before he went in some man walked up to him (he didn't know him) and asked if he could pray with him. (This man had no idea he had just left treatment). Then the man gave this boy his phone number and the boy went back to treatment. When he attempted to call this man, the number didn't work. He is still in treatment and now has a more positive attitude about getting better.
