(3.) He promises them a share in his glory hereafter (v. 17): They shall be mine, saith the Lord of hosts, in that day when I make up my jewels. When God utterly cuts off the Jewish church and nation for their infidelity, the remnant among them, that believed his word, and, having waited for the consolation of Israel, welcome him when he comes, shall be admitted into the Christian church, and shall become a peculiar people to God; God will take care of them, that they perish not with those that believe not; but that they be hidden in the day of the Lord's anger against that nation. They shall be my segullah—my peculiar treasure (it is the word used, Exod. xix. 5), in the day when I make or do what I have said and designed to do; so some read it. These pious ones shall have all the glorious privileges of God's Israel appropriated to them and centering in them; they shall now be his peculiar treasure, when the rest are rejected; they shall now be the vessels of mercy and honour, when the rest are made vessels of wrath and dishonour, vessels in which is no pleasure. This may be applied to all the faithful people of God, and the distinction he will put between them and others in the great day. Note, [1.] The saints are God's jewels; they are highly esteemed by him and are dear to him; they are comely with the comeliness that he puts upon them, and he is pleased to glory in them; they are a royal diadem in his hand, Isa. lxii. 3. He looks upon them as his own proper goods, his choice goods, his treasure, laid up in his cabinet, and the furniture of his closet, Ps. cxxxv. 4. The rest of the world is but lumber, in comparison with them. [2.] There is a day coming when God will make up his jewels. They shall be gathered up out of the dirt into which they are now thrown, and gathered together from all places to which they are now scattered; he shall send forth his angels to gather his elect, who are his jewels, from the four winds of heaven (Matt. xxiv. 31), to gather his jewels into his jewel-house, as the wheat from several fields into the barn. All the saints will then be gathered to Christ, and none but saints, and saints made perfect; then God's jewels will be made up, as stones into a crown, as stars into a constellation. [3.] Those who now own God for theirs, he will then own for his, will publicly confess them before angels and men: "They shall be mine; their sanctification shall be completed, and so they shall be perfectly and entirely mine, without any remaining interests of the world and the flesh." Their relation to God shall be acknowledged, and his property in them. He will separate them from those that are not his, and give them their portion with those that are his; for to them it shall be said, Come, you blessed of my Father, inherit the kingdom prepared for you. They were in doubt, sometimes, whether they were belonging to God or no; but the matter shall then be put out of doubt. God himself will say unto them, You are mine. Now their relation to God is what they are reproached with, but it will then be gloried in; God himself will glory in it.
