III. The safety and happiness of all true believers both in the first and second coming of Jesus Christ, v. 32. This speaks of particular persons, for to them the New Testament has more respect, and less to kingdoms and nations, than the Old. Now observe here, 1. That there is a salvation wrought out. Though the day of the Lord will be great and terrible, yet in Mount Zion and in Jerusalem there shall be deliverance from the terror of it. It is the day of the Lord, the day of his judgment, who knows how to separate between the precious and the vile. In the everlasting gospel, which went from Zion, in the church of the first-born typified by Mount Zion, and which is the Jerusalem that is from above, there is deliverance; a way of escaping the wrath to come is found out and laid open. Christ is himself not only the Saviour, but the salvation; he is so to the ends of the earth. This deliverance, laid up for us in the covenant of grace, is in performance of the promises made to the fathers. There shall be deliverance, as the Lord has said. See Luke i. 72. Note, This is ground of comfort and hope to sinners, that, whatever danger there is in their case, there is also deliverance, deliverance for them, if it be not their own fault. And, if we would share in this deliverance, we must ourselves apply to the gospel—Zion, to God's Jerusalem. 2. That there is a remnant interested in this salvation, and for whom the deliverance is wrought. It is in that remnant (that is, among them) that the deliverance is, or in their souls and spirits; there are the earnests and evidences of it. Christ in you, the hope of glory. They are called a remnant, because they are but a few in comparison with the multitudes that are left to perish; a little remnant but a chosen one, a remnant according to the election of grace. And here we are told who they are that shall be delivered in the great day. (1.) Those that sincerely call upon God: Whosoever shall call upon the name of the Lord, whether Jew or Gentile (for the apostle so expounds it, Rom. x. 13, where he lays this down as the great rule of the gospel by which we must all be judged), shall be delivered. This calling on God supposes knowledge of him, faith in him, desire towards him, dependence on him, and, as an evidence of the sincerity of all this, a conscientious obedience to him; for, without that, crying Lord, Lord, will not stand us in any stead. Note, It is the praying remnant that shall be the saved remnant. And it will aggravate the ruin of those who perish that they might have been saved on such easy terms. (2.) Those that are effectually called to God. The deliverance is sure to the remnant whom the Lord shall call, not only with the common call of the gospel, with which many are called that are not chosen, but with a special call into the fellowship of Jesus Christ, whom the Lord predestinates, or prepares, so the Chaldee. St. Peter borrows this phrase, Acts ii. 39. Note, Those only shall be delivered in the great day that are now effectually called from sin to God, from self to Christ, from things below to things above.
