This prayer is the climax of David’s reign as he awaits the building of the Temple in 1 Chronicles 29:10-18. He is praising God for his sovereignty and his promises. And some of the language in this prayer is even used by John in Revelation when he gets a glimpse of God’s heavenly Temple and throne room.

Blessed are you, the God of Israel, 
Our Father, forever and ever. 
Yours, O Lord, is the greatness, 
And the power and the glory, 
And the victory and the majesty, 
For all that is in the heavens and in the earth is yours. 
Yours is the kingdom, O Lord, 
And you are exalted as head above all. 
Both riches and honor come from you, 
And you rule over all. 
In your hands are power and might, 
And in your hands it is to make great. 
And now we thank you, our God, 
And praise your glorious name. 
But who am I, and who are these people, 
That we should be able to offer to you willingly? 
For all things come from you, 
And of your own we have given back to you. 
For we are strangers before you and sojourners, as our fathers were.
Our days on the earth are like a shadow, they do not abide.
I know, O God, that you test the heart and delight in uprightness.
And in the uprightness of my heart, I have freely offered these things. 
O Lord, the God of Abraham, Isaac, and Israel, 
Keep forever the hearts of your people, 
And direct their hearts toward you. 
We praise you, O Lord God, our Father, 
And bow low before you this day.
