1 Kings 8:17-19 “My father David had it in his heart to build a temple for the Name of the Lord, the God of Israel. But the Lord said to my father David, ‘You did well to have it in your heart to build a temple for my Name. Nevertheless, you are not the one to build the temple, but your son, your own flesh and blood—he is the one who will build the temple for my Name.’ 
There will be things in my heart that I want to do for the Lord, but some of these things are destined to be fulfilled not by me, but will instead be done by my children.
