1. Sing unto Jehovah a new song. This commencement shows that, as I have already observed, the Psalmist is exhorting the whole world, and not the Israelites merely, to the exercise of devotion. Nor could this be done, unless the gospel were universally diffused as the means of conveying the knowledge of God. The saying of Paul must necessarily hold true,
“How shall they call upon him in whom they have not believed?” (<451014>Romans 10:14.)
The same Apostle proves the calling of the Gentiles, by adducing in testimony of it, “Praise the Lord, ye Gentiles, with his people” — from which it follows, that fellowship in the faith stands connected with the joint celebration of praise, (<451511>Romans 15:11.) Besides, the Psalmist requires a new song, fd75not one which was common, and had formerly been raised. He must therefore refer to some unusual and extraordinary display of the Divine goodness. Thus, when Isaiah speaks of the restoration of the Church, which was wonderful and incredible, he says, “Sing unto the Lord a new song,” (<234210>Isaiah 42:10.) The Psalmist intimates accordingly, that the time was come when God would erect his kingdom in the world in a manner altogether unlooked for. He intimates still more clearly as he proceeds, that all nations would share in the favor of God. He calls upon them everywhere to show forth his salvation, and, in desiring that they should celebrate it from day to day, would denote that it was not of a fading or evanescent nature, but such as should endure for ever.
3. Declare his glory among the heathen. Additional terms are adduced to commend the salvation spoken of. It is called his glory and his wonders; which is equivalent to saying that it was glorious and admirable. By such titles the Psalmist would distinguish it from any deliverances which had formerly been granted, as indeed there can be but one opinion, that when God appeared as Redeemer of all the world, he gave a display of his mercy and of his favor, such as he never vouchsafed before. This salvation it was impossible, as I have said, that the Gentile nations could have celebrated, had they been left without it. The words teach us that we can never be said to have rightly apprehended the redemption wrought out by Christ, unless our minds have been raised to the discovery of something incomparably wonderful about it.
