Charles H. Spurgeon on Psalms 72:17

His name shall endure for ever. In its saving power, as the rallying point of believers, and as renowned and glorified, his name shall remain for ever the same. His name shall be continued as long as the sun. While time is measured out by days, Jesus shall be glorious among men. And men shall be blessed in him. There shall be cause for all this honour, for he shall really and truly be a benefactor to the race. He himself shall be earth's greatest blessing; when men wish to bless others they shall bless in his name. All nations shall call him blessed. The grateful nations shall echo his benedictions, and wish him happy who has made them happy. Not only shall some glorify the Lord, but all; no land shall remain in heathenism; all nations shall delight to do him honour.

Verses 18-19. As Quesnel well observes, these verses explain themselves. They call rather for profound gratitude, and emotion of heart, than for an exercise of the understanding; they are rather to be used for adoration than for exposition. It is, and ever will be, the acme of our desires, and the climax of our prayers, to behold Jesus exalted King of kings and Lord of lords. He has done great wonders such as none else can match, leaving all others so far behind, that he remains the sole and only wonder worker; but equal marvels yet remain, for which we look with joyful expectation. He is the Blessed God, and his name shall be blessed; his name is glorious, and that glory shall fill the whole earth. For so bright a consummation our heart yearns daily, and we cry Amen, and Amen.
