1 Chronicles 28:6
And he said unto me, Solomon thy son, he shall build my house and my courts: for I have chosen him to be my son, and I will be his father. And he said unto me, Solomon thy son, he shall build my house and my courts: for I have chosen him to be my son, and I will be his father.
God chose Solomon to build His house and its courts. The same choice is recorded as God's assurance authorizing Solomon's role in the temple project. In choosing him, God established a father-son relationship with him: Solomon would be His son and He would be Solomon's Father, God regarding Solomon as His son and being his Father. The God who speaks is the Lord God of Israel and ruler of all the world, and the Solomon He chose was the son of Bathsheba. The choice appointed Solomon to succeed David and be king after David's death.
This was a divine appointment within Israel's theocracy, and the promise authorized Solomon's role in the temple project. With the choice came promise of blessing and an enduring kingdom, even establishment of Solomon's kingdom forever, but its continuation was conditional on his faithfulness and obedience in keeping God's commandments and judgments. David was not to do the building work himself; he could prepare, advise, counsel and encourage, but carrying out the task God had given belonged to Solomon, his younger successor, David's son, whose experience and preparations could help him counsel and encourage Solomon while the younger man was to carry out the task. The arrangement shows that God assigns different people different parts of His work, and that experienced workers should make room for those He qualifies to carry it forward.
The chapter containing the verse is important for God's people in every age, teaching that those entrusted with sacred responsibilities should have genuine experience and dependable character, fitting them to serve God and represent a people set apart for Him, the verse's setting showing God appointing Solomon to build the house and courts. David knew Solomon alone of all his sons was qualified to rule his people because he kept the love of God before him. Solomon was especially beloved by God, yet he later turned from God by marrying heathen women in violation of the law against such marriages; they led him into idolatry, and he built places for their idols, though God had chosen him to build the temple and called him His son, promising to be his Father.
