The use made of this psalm in the Epistle to the Hebrews proceeds on the understanding that it describes ideal humanity. Where, then, says the writer of the epistle, shall we look for the realisation of that ideal? Do not the grand words sound liker irony than truth? Is this poor creature that crawls about the world, its slave, discrowned and sure to die, the Man whom the psalmist saw? No. Then was the fair vision a baseless fabric, and is there nothing to be looked for but a dreary continuance of such abortions dragging out their futile being through hopeless generations? No; the promise shall be fulfilled for humanity, because it has been fulfilled in one Man: the Man Christ Jesus. He is the realised ideal, and in Him is a life which will be communicated to all who trust and obey Him, and they, too, will become all that God meant man to be. The psalm was not intended as a prophecy, but every clear vision of God's purpose is a prophecy, for none of His purposes remain unfulfilled. It was not intended as a picture of the Christ, but it is so; for He, and He alone, is the Man who answers to that fair Divine Ideal, and He will make all His people partakers of His royalty and perfect manhood.
So the psalm ends, as it began, with adoring wonder, and proclaims this as the result of the twofold witness which it has so nobly set forth: that God's name shines glorious through all the earth, and every eye may see its lustre.
