I understand what you are saying but I, I, and myself does not save anyone....we plant, we water and God gives the increase....
You know....our society makes much ado about numbers and at the end of the day some of the greatest men/preachers of the bible would have been considered complete failures by our modern line of thought...for example....
Noah preached a LONG time and only 5 other than Noah believed....
Jesus at one time only had 11-12 and was worried that they would leave him and in deed did scatter the night he was smitten.
You know, I have witnessed, preached, written a book, been on radio, TV and internet for the last 25 or so years off and on and have not worried once about the numbers as it is God that gives the increase and in my view...even if it is only ONE...it was worth it!
