Exodus 3: 1-15 -- Called by God

This is a little from both 9 and 10:30.  The scripture reading and introduction is from 9 and the actual sermon is from 10:30.  Moses is called by God.  He key is the issue of "po" (here) and "hineni" (here I am but with a spiritual commitment.)  Probably need to listen close to the sermon but when getting ready to exit a USAF aircraft, while still in flight, the commitment is made by a statement of "All OK".  In.  100% in and ready.
