12:18-29 Mount Sinai, on which the Jewish church state was formed, was a mount such as might be touched, though forbidden to be so, a place that could be felt; so the Mosaic dispensation was much in outward and earthly things. The gospel state is kind and condescending, suited to our weak frame. Under the gospel all may come with boldness to God's presence. But the most holy must despair, if judged by the holy law given from Sinai, without a Saviour. The gospel church is called Mount Zion; there believers have clearer views of heaven, and more heavenly tempers of soul. All the children of God are heirs, and every one has the privileges of the first-born. Let a soul be supposed to join that glorious assembly and church above, that is yet unacquainted with God, still carnally-minded, loving this present world and state of things, looking back to it with a lingering eye, full of pride and guile, filled with lusts; such a soul would seem to have mistaken its way, place, state, and company. It would be uneasy to itself and all about it. Christ is the Mediator of this new covenant, between God and man, to bring them together in this covenant; to keep them together; to plead with God for us, and to plead with us for God; and at length to bring God and his people together in heaven. This covenant is made firm by the blood of Christ sprinkled upon our consciences, as the blood of the sacrifice was sprinkled upon the altar and the victim. This blood of Christ speaks in behalf of sinners; it pleads not for vengeance, but for mercy. See then that you refuse not his gracious call and offered salvation. See that you do not refuse Him who speaketh from heaven, with infinite tenderness and love; for how can those escape, who turn from God in unbelief or apostacy, while he so graciously beseeches them to be reconciled, and to receive his everlasting favour! God's dealing with men under the gospel, in a way of grace, assures us, that he will deal with the despisers of the gospel, in a way of judgment. We cannot worship God acceptably, unless we worship him with reverence and godly fear. Only the grace of God enables us to worship God aright. God is the same just and righteous God under the gospel as under the law. The inheritance of believers is secured to them; and all things pertaining to salvation are freely given in answer to prayer. Let us seek for grace, that we may serve God with reverence and godly fear.

27. this word, Yet once more—So Paul, by the Spirit, sanctions the Septuagint rendering of Hag 2:6, giving an additional feature to the prophecy in the Hebrew, as rendered in English Version, not merely that it shall be in a little while, but that it is to be "once more" as the final act. The stress of his argument is on the "ONCE." Once for all; once and for ever. "In saying 'once more,' the Spirit implies that something has already passed, and something else shall be which is to remain, and is no more to be changed to something else; for the once is exclusive, that is, not many times" [Estius].

those things that are shaken—the heaven and the earth. As the shaking is to be total, so shall the removal be, making way for the better things that are unremovable. Compare the Jewish economy (the type of the whole present order of things) giving way to the new and abiding covenant: the forerunner of the everlasting state of bliss.

as of things … made—namely, of this present visible creation: compare 2Co 5:1; Heb 9:11, "made with hands … of this creation," that is, things so made at creation that they would not remain of themselves, but be removed. The new abiding heaven and earth are also made by God, but they are of a higher nature than the material creation, being made to partake of the divine nature of Him who is not made: so in this relation, as one with the uncreated God, they are regarded as not of the same class as the things made. The things made in the former sense do not remain; the things of the new heaven and earth, like the uncreated God, "shall REMAIN before God" (Isa 66:22). The Spirit, the seed of the new and heavenly being, not only of the believer's soul, but also of the future body, is an uncreated and immortal principle.
