From the additional notes to Charles Spurgeon's The Treasury of David, on Psalm 115.
Verse 1. There are many sweet and precious texts of Scripture which are so endeared, and have become so habituated to us, and we to them, that one cannot but think we must carry them with us to heaven, and that they will form not only the theme of our song, but a portion of our blessedness and joy even in that happy home... But if there be one text which more especially belongs to all, and which must, I think, break forth from every redeemed one as he enters heaven, and form the unwearying theme of eternity, it is the first verse of this Psalm.
I am sure that not one of the Lord's chosen ones on earth, as he reviews the way by which he has been led, as he sees enemy after enemy prostrate before his utter feebleness, and has such thorough evidence and conviction that his weakness is made perfect in the Lord's strength, but must, from the very ground of his heart, say, Not unto us, O LORD, not unto us, but unto thy name be the praise and the glory ascribed. And could we see heaven opened—could we hear its glad and glorious hallelujahs—could we see its innumerable company of angels, and its band of glorified saints, as they cast their crowns before the throne, we should hear as the universal chorus from every lip, "Not unto us, O LORD, not unto us, but unto thy name give glory, for thy mercy, and for thy truth's sake. I know not why this should not be as gladly and as gratefully the angels' song as the song of the redeemed: they stand not in their own might nor power,—they kept not their first estate through any inherent strength of their own, but, like their feebler brethren of the human race, are equally "kept by the power of God"; and from their ranks, I doubt not, is re-echoed the same glorious strain, "Not unto us, O LORD, not unto us, but unto thy name give glory."
Even our blessed Lord, as on that night of sorrow he sung this hymn of praise, could truly say, in that nature which had sinned, and which was to suffer, "Not unto us," — not unto man, be ascribed the glory of this great salvation, which I am now with my own blood to purchase, but unto thy name and thy love be the praise given.
