When David prays for the people and for Solomon, he prays that they may be faithful, as faithful as the day they started serving God. He calls into being the covenant that God made with Abraham, Isaac and Jacob. He is thankful that God gives grace so that we can make good our part of the covenant and thereby not lose its benefits. For the people he prays that what God had put in their minds, He would keep there. He prays that they will never be worse than they were now, never losing their convictions nor cool to their affections to the house of God. There were great consequences either way – everything depended on their hearts, what they were trying to grasp and what they loved to think about.

Give my son Solomon a wholehearted desire to obey everything that you command and to build the Temple for which I have made these preparations. – 2 Chronicles 29:19 GNT

It is good to commit to God, by prayer, the custody of those that matter most to the grace of God. When I am gone, God keep them. In fact, give them a wholehearted desire to obey and to serve You. I love the fact that he did not pray for riches or greatness – just that he might be an honest man with a focus on his God.

Then David commanded the people, “Praise the Lord your God!” And the whole assembly praised the Lord, the God of their ancestors, and they bowed low and gave honor to the Lord and also to the king. – 2 Chronicles 29:20 GNT

What a way to bless God.

There are few converted in this world unless in connection with some one’s prayers. I formerly thought that no human being had anything to do with my own conversion, for I was not converted in church or Sunday-school, or in personal conversation with any one. I was awakened in the middle of the night and converted. As far as I can remember I had not the slightest thought of being converted, or of anything of that character, when I went to bed and fell asleep; but I was awakened in the middle of the night and converted probably inside of five minutes. A few minutes before I was about as near eternal perdition as one gets. I had one foot over the brink and was trying to get the other one over. I say I thought no human being had anything to do with it, but I had forgotten my mother’s prayers, and I afterward learned that one of my college classmates had chosen me as one to pray for until I was saved. – R.
