2. (Mal 4:1; Re 6:16, 17). The Messiah would come, not, as they expected, to flatter the theocratic nation's prejudices, but to subject their principles to the fiery test of His heart-searching truth (Mt 3:10-12), and to destroy Jerusalem and the theocracy after they had rejected Him. His mission is here regarded as a whole from the first to the second advent: the process of refining and separating the godly from the ungodly beginning during Christ's stay on earth, going on ever since, and about to continue till the final separation (Mt 25:31-46). The refining process, whereby a third of the Jews is refined as silver of its dross, while two-thirds perish, is described, Zec 13:8, 9 (compare Isa 1:25).

     3. sit—The purifier sits before the crucible, fixing his eye on the metal, and taking care that the fire be not too hot, and keeping the metal in, only until he knows the dross to be completely removed by his seeing his own image reflected (Ro 8:29) in the glowing mass. So the Lord in the case of His elect (Job 23:10; Ps 66:10; Pr 17:3; Isa 48:10; Heb 12:10; 1Pe 1:7). He will sit down to the work, not perfunctorily, but with patient love and unflinching justice. The Angel of the Covenant, as in leading His people out of Egypt by the pillar of cloud and fire, has an aspect of terror to His foes, of love to His friends. The same separating process goes on in the world as in each Christian. When the godly are completely separated from the ungodly, the world will end. When the dross is taken from the gold of the Christian, he will be for ever delivered from the furnace of trial. The purer the gold, the hotter the fire now; the whiter the garment, the harder the washing [MOORE].
