Charles H. Spurgeon on Psalms 98:8

Though the language be figurative, so far as it gives a voice to the inanimate creation in its various departments, yet, like all the figurative language of Scripture, it expresses a truth —that which the Apostle has stated without a metaphor in the express revelation that the "creation shall be delivered from the bondage of corruption into the glorious liberty of the children of God." And this because the reason of that bondage will no more exist. It is the consequence of sin: but when the world shall be subjected to the righteous rule of its coming King (as predicted in the last verse of this psalm), then earth and all creation shall own its present Lord, and join its tribute of praise to that of Israel and the nations, and the redeemed and glorified chinch. William De Burgh.
