Malachi 3:18 - Albert Barnes' Notes on the Bible

Then shall ye return, or turn - , not, “return” in the sense of returning to God, for in that day will be the time of judgment, not of repentance; nor yet, “then shall ye again see;” for this is what they denied; and, if they had ceased to deny it, they would have been converted, not in that day, but before, when God gave them grace to see it. They shall turn, so as to have other convictions than before; but, as Judas. The Day of Judgment will make a great change in earthly judgment. Last shall be first and first last; this world’s sorrow shall end in joy, and worldly joy in sorrow; afflictions shall be seen to be God’s love: Psalms 119:75, “Thou in very faithfulness hast afflicted me;” and the unclouded prosperity of the ungodly to be God’s abandonment of them. The picture of the surprise of the wicked in the Day of Judgment, in the Wisdom of Solomon, is a comment on the prophet (Wisdom 5:1-5), “Then shall the righteous man stand in great boldness before the face of such as have afflicted him, and made no account of his labors; when they see it, they shall be troubled with terrible fear, and shall be amazed with the strangeness of his salvation, so far beyond all they looked for: and they, repenting and groaning for anguish of spirit, shall say within themselves, This was he whom we had sometimes in derision and a proverb of reproach: we fools counted his life madness and his end to be without honor: how is he numbered among the children of God, and his lot is among the saints!”
