I Chronicles 24:1 - II Chronicles 7:10
David had a heart to build God's house but God said no.
"But God said unto me, Thou shalt not build an house for my name, because thou hast been a man of war, and hast shed blood."
II Chr. 28:3
Now David could have pouted and thrown a fit about God's decision. He could have wasted years being angry with God and Solomon; However, he chose to get busy. He gathered the items, supplies, and tools for his son Solomon to build the temple.
"Now I have prepared with all my might for the house of my God the gold for things to be made of gold, and the silver for things of silver, and the brass for things of brass, the iron for things of iron, and wood for things of wood; onyx stones, and stones to be set, glistering stones, and of divers colours, and all manner of precious stones, and marble stones in abundance." I Chr. 29:2
Solomon has everything he could possibly need to build a house for the Lord. Solomon finishes the temple.
"Thus all the work that Solomon made for the house of the Lord was finished: and Solomon brought in all the things that David his father had dedicated; and the silver, and the gold, and all the instruments, put he among the treasures of the house of God."
II Chr. 5:1
Sometimes we are just the see sower. Our job is to just plant seeds for the Lord. We are preparing hearts for the Lord. Then someone else comes along and reaps the harvest. As long as God's plan is fulfilled, that is all that should matter. We are a part of something much greater.
