Psalm 36:7 “How precious is your unfailing love, O God! People take refuge in the shadow of your wings.” There is not a person on earth who has not failed multiple times.  A common rule of failure is 80% success and 20 % failure, and a persistence will make a person very successful.  The rule God follows is: 100% success and 0% failure.  When God says –you can count on Me, I will never fail you, My love for you never fails==He is speaking 100% truth.  That is impossible to bet.
