I have been there.  i have been 4" from placing the ***** in my mouth and going home early.  How do you come back from there?  You trust God. You move on into whatever He has next.
I sat in the woods with a 30-30 pointed at my head and the ***** cocked.  When it got to my mouth I had to pull the trigger.
4 inches. 
It was that close but God pulled me back.  I sit often and wonder why God stopped me.  What is next for me, for you?  God is the answer now we need to simply work out the question.  Join me in the journey.
