Psalms 66:4

Also in this place (which we have been quoting), the apostle to the Gentiles said that the wrath of God comes on the children of infidelity because of these evils. When, however, he says, "And you yourselves once walked in them when they were your life," he shows well enough that they were not their life then. To them, indeed, they were dead, since their life was hidden with Christ in God. For the evils, in truth, were living in those who were not living in the evils, as I indicated a little while ago. Likewise, the vices, indeed, that were dwelling in the members of certain people were said to be their members, by a figure of speech in which the name of a place is given to the things contained within it, just as it is said that the whole forum speaks when what is meant is that the people who are in the forum are speaking. By this same figure of speech, there is sung in the psalm, "Let all the earth adore you," that is, all people who are on the earth.

In gospel times God shall be worshipped by the singing of Psalms. They shall sing to God, that is, sing to his name, for it is only to his declarative glory, that by which he has made himself known, not to his essential glory, that we can contribute any thing by our praises.

All the earth shall worship thee, and shall sing unto thee. All men must even now prostrate themselves before thee, but a time will come when they shall do this cheerfully; to the worship of fear shall be added the singing of love. What a change shall have taken place when singing shall displace sighing, and music shall thrust out misery! They shall sing to thy name. The nature and works of God will be the theme of earth's universal song, and he himself shall be the object of the joyful adoration of our emancipated race.

The nature and works of God will be the theme of earth's universal song, and he himself shall be the object of the joyful adoration of our emancipated race. Acceptable worship not only praises God as the mysterious Lord, but it is rendered fragrant by some measure of knowledge of his name or character. God would not be worshipped as an unknown God, nor have it said of his people, "Ye worship ye know not what." May the knowledge of the Lord soon cover the earth, that so the universality of intelligent worship may be possible: such a consummation was evidently expected by the writer of this Psalm; and, indeed, throughout all Old Testament writings, there are intimations of the future general spread of the worship of God. It was an instance of wilful ignorance and bigotry when the Jews raged against the preaching of the gospel to the Gentiles. Perverted Judaism may be exclusive, but the religion of Moses, and David, and Isaiah was not so. Selah. A little pause for holy expectation is well inserted after so great a prophecy, and the uplifting of the heart is also a seasonable direction. No meditation can be more joyous that excited by the prospect of a world reconciled to its Creator.

All the earth - The whole land shall worship thee. There shall no more an idol be found among the tribes of Israel. This was iterally true. After the Babylonish captivity the Israelites never relapsed into idolatry. Selah - Remark it: this is a well attested truth.
