Adam Clarke's Bible Commentary Verse 4. His lightnings enlightened the world ] Though this be no more than a majestic description of the coming of the Lord, to confound his enemies and succour his followers, yet some spiritualize the passage, and say, the lightnings signify the apostles, who enlightened the world by their heavenly doctrine.
The earth saw, and trembled. ] The earth is represented as a sentient being. It saw the terrible majesty of God; and trembled through terror, fearing it should be destroyed on account of the wickedness of its inhabitants.
Matthew Henry Commentary
Verses 1-7 - Though many have been made happy in Christ, still there is room. An all have reason to rejoice in Christ's government. There is a depth in his counsels, which we must not pretend to fathom; but stil righteousness and judgment are the habitation of his throne. Christ' government, though it might be matter of joy to all, will yet be matte of terror to some; but it is their own fault that it is so. The mos 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 ido worship of every kind.
