Matthew Henry on Psalms 97:1-7

Though many have been made happy in Christ, still there is room. And all have reason to rejoice in Christ's government. There is a depth in his counsels, which we must not pretend to fathom; but still righteousness and judgment are the habitation of his throne. Christ's government, though it might be matter of joy to all, will yet be matter of terror to some; but it is their own fault that it is so. The most resolute and daring opposition will be baffled at the presence of the Lord. And the Lord Jesus will ere long come, and put an end to idol worship of every kind.
