Significance of the Number 13...

Conviction set in on the 13th birthday of my youngest daughter, Joni.  What was this significant thing?  After years of procrastination, number 13 became not a lucky number but a blessed number.  Let's rule out that I don't believe in numerology.  Something important happened when on July 13, 2011, I decided beyond my usual procrastination, to step out in faith and pursue a Doctorate in Ministry degree.   Since serving as a pastor for the past 13 years in Southeastern California Conference, (the greatest conference in North America Division if not the world field), I turned in my application form.  That's three coincidental number 13 references.   The last reference to number 13 is that I've served a total 31 years of pastoral service in several churches in California (31 backwards is 13).  What in the world is going on?  I'm not sure I know myself, other than number 13 is my new favorite, if not blessed number!  I may even consider buying a sports jersey with number 13 on it!
