Charles Spurgeon Commentary 2 Samuel 7:21-25

"For thy word`s sake, and according to thine own heart, hast thou wrought all this greatness, to make thy servant know it. Wherefore thou art great, O Jehovah God: for there is none like thee, neither is there any God besides thee, according to all that we have heard with our ears. And what one nation in the earth is like thy people, even like Israel, whom God went to redeem unto himself for a people, and to make him a name, and to do great things for you, and terrible things for thy land, before thy people, whom thou redeemest to thee out of Egypt, [from] the nations and their gods? And thou didst establish to thyself thy people Israel to be a people unto thee for ever; and thou, Jehovah, becamest their God. And now, O Jehovah God, the word that thou hast spoken concerning thy servant, and concerning his house, confirm thou it for ever, and do as thou hast spoken." — 2 Samuel 7:21-25 (ASV)

For thy word's sake, and according to thine own heart, hast thou done all these great things, to make thy servant know them.

Wherefore thou art great, O LORD God: for there is none like thee, neither is there any God beside thee, according to all that we have heard with our ears. And what one nation in the earth is like thy people, even like Israel, whom God went to redeem for a people to himself, and to make him a name, and to do for you great things and terrible, for thy land, before thy people, which thou redeemest to thee from Egypt, from the nations and their gods? For thou hast confirmed to thyself thy people Israel to be a people unto thee for ever: and thou, LORD, art become their God. And now, O LORD God, the word that thou hast spoken concerning thy servant, and concerning his house, establish it for ever, and do as thou hast said.

That is a very short, but exceedingly pithy prayer: "Do as you have said." You do not need any larger promises, brothers, than the Lord has already given to you: could he give you any larger ones?

"What more can he say than to you he has said,
You who to Jesus for refuge have fled?"

What you have to do is to take the promises he has given, and spread them out before the mercy seat, and then say to him, "Do as you have said." What strength there is in this plea! Has he said, and shall he not do it? "Will he break his promise, or shall his right hand fail to perform that which has gone forth from his lips? Far be it from us to think so, but let us say to him, "Do as you have said." That is the very essence of prayer. Take care not to forget it.
