v1-2: Another sign of God's approval, as in 5.13-14. Fire from Heaven and the glory of God.
v3-6: The people responded in praise to God; they bowed their faces to the ground and worshipped God.
They offered sacrifices, as God had laid down in the Law. Their worship also included music, which David had promoted; their instruments were used specifically for worship of God. The people, seeing and listening, stood attentively.
v7: Although the altar was huge, it was not large enough for all the offerings.
v8-10: The Feast of Tabernacles followed the dedication of the altar.
v11-12: Solomon's prayers were answered; "I have heard your prayer." God had demonstrated His approval, but here He also told Solomon. Such is God's grace that He should bless an imperfect people.
v13: The disasters that would befall Israel would come from the hand of God, and then there was an opportunity for respite and deliverance. Today’s enjoyment of God’s blessing would not continue.
v14: The prayer to God had to include genuine repentance; the people must humble themselves, pray and seek His face, and turn from their wicked ways, and then God would answer, and heal their land. This scripture is one of those frequently wrenched from its context.
v15: "This place", chosen and honoured by God. For us, Jesus Christ is chosen and honoured by God, John 16.33.
v16: There were promises "for ever", an ongoing future blessing, not dependent on Israel itself. It was this promise that Daniel knew, see Dan 6.10.
v17-18: The condition of blessing was personal obedience to God. God had great things in store for His people, but they would miss out on blessing if they were disobedient.
v19-22: The temple was a sign of God's faithfulness. It would be a witness against the people if they turned from the Lord God; this would still demonstrate His faithfulness, but would also testify to their folly, in turning from the True and Living God. Although they would become faithless, He would not deny Himself, see 2 Tim 2.12-13.
Rom 2.24 indicates that such judgments did fall upon Israel; such disobedience also brings dishonour to the Name of God.
