And they shall be Mine, saith the Lord of hosts, in that day when I make up My jewels - o the recurrence of the words, עשה אני אשר יום, Mal. 3:21. Hebrew (Malachi 4:3 in English), and the סגלה לי והייתםExo. 19:5; so that we have both phrases elsewhere. In Deuteronomy 7:6, there is the equivalent לעם לו להיות סגלה, and the like, Deuteronomy 14:2; Psalms 135:4.) or perhaps better, “And they shall be to Me, saith the Lord of hosts, in that day which I make (or, in which I do this) a special treasure.” “In the day of judgment, those who fear Me and believe and maintain My providence shall be to Me a special treasure, i. e., a people uniquely belonging and precious to Me, blessed in the vision and fruition of Me. For as in the old law, Israel was a special treasure a special people and inheritance of God, chosen out of all nations, so in the new law, Christians, and those who are righteous through grace, are the special treasure of God, and in heaven shall be His special treasure in glory, possessed by God and possessing God.’ The “special treasure,” is something, much prized, made great store of, and guarded. Such are Christians, bought at a great price, even by the precious Blood of Christ; but much more evidently such shall they be, Malachi says, in all eternity, which that day of final retribution shall decide , “joying in the participation of their Creator, by Whose eternity they are fixed, by Whose truth they are assured, by Whose gift they are holy.”
And I will spare them - It is a remarkable word, as used of those who should be to Him a “special treasure,” teaching that, not of their own merits, they shall be such, but by His great mercy. It stands in contrast with the doom of the wicked, whom that day shall sentence to everlasting less of God. Still, the saved also shall have needed the tender mercy of God, whereby He pardoned their misdeeds and had compassion upon them Psalms 130:3, “If Thou, Lord, shalt lay up iniquities, O Lord, who shall stand?” Among those whom God will spare on that day, will be countless, whom the self-righteous despised as sinners. “I will spare them, although formerly sinners; I will spare them, repenting, and serving Me with the service of a pious confession, as a man spareth his own son which served him.” For our Lord saith of the son, who refused to go work in his Father’s vineyard, and afterward repented and went, that he Matthew 21:31, “did the will of his Father.”
