A LABOR OF LOVE

What if our children only did something for us because they "knew" or "expected" some GREAT REWARD?  They would do "some things" when they took the time, but soon they feel the REWARD needs to be greater or "IT'S JUST NOT WORTH THE EFFORT".  Do WE WORK FOR JESUS because we are expecting A GREATER REWARD?  Hebrews 5:6, "...without Faith it is impossible to please HIM, for those who draw near to GOD can not do it without BELIEVING IN HIM, HE REWARDS those who SEEK HIM".  Could WORK be SEEKING the fulfillment of HIS HOLINESS and the REVERENCE in HIS PRESENCE?  Could WORK be the MIRACLES OF LOVE?  DO WE "WORK" FOR HIS REWARD; OR IS THE  REWARD IN OUR DESIRE FOR HIM?  AND, IS "WORK", ACTUALLY,  A LABOR OF LOVE?
