v1-2: David's desire was to see God honoured. He had no plans for his own glory, 1 Sam 13.14; contrast Hag 1.4. This is a challenge to our personal priorities.
v3-6: The disappointment of God's answer. This came immediately, so that David did not build up his hopes and aspirations; although David was the man after God's heart, he still had to submit to God in all things.
v7-8: God had other blessings for David.
v9-10: God's blessing upon Israel. This reflected David's concern for his people; David would not expect God to speak only about personal blessings. God promised that Israel would be planted in their place, free from oppression, and their enemies subdued.
v11-14: God would establish the kingdom of Israel through David's son, Solomon. The promises of God are clear here;
- that David's offspring would reign after him;
- that his offspring's kingdom would be established;
- that his offspring would build a house for God;
- that there will be a father-son relationship;
- that his offspring will never lose the love of God;
- that he will be set over God's house and kingdom.
Although there was some fulfilment in the life of Solomon, it is clear that these words refer to the Lord Jesus Christ, the Son of David. Christ is called the root and offspring of David. In particular, the kingdom of God established through Christ cannot be destroyed.
v15: Nathan faithfully reported the words of God to David.
v16: David's response was in thankfulness and devotion, without a hint of grumbling. Eight times in v16-27 comes the word "O", indicating his devotion. This is indeed the prayer of the man after God's own heart.
v17: David's gratitude that God had made promises about his family. David states that he is undeserving of such blessings.
v18: God had honoured His servant, and David was grateful.
v19: God will honour His promises, which find their source in God's grace.
v20: David declares the uniqueness of God; there is none like Him.
v21-22: The people of God are also unique; the only nation that God has redeemed for Himself. Thus there is great privilege in being the people of God. Israel came into a relationship with God.
v23-24: David's prayer was that God's word would be true, and that His Name be magnified, and that his house be established, thus that the promises of God would be fulfilled. Contrast 2 Sam 23.5, "my house is not so with God".
v25-27: David brings his prayer to a conclusion, overwhelmed with thankfulness that God has plans for him, his family, and his nation. "You, O Lord, have blessed it, and it will be blessed for ever", compare Gen 27.33; Ps 102.26; Is 14.27.
