(29) A quotation from Deuteronomy 4:24. There these words follow a solemn warning against idolatry. This passage then belongs to the same class as Hebrews 10:27-28; Hebrews 10:30. (See the Notes.)

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.For our God is a consuming fire. Either God personally considered, God in the person of Christ; so the Shechinah, with the Jews, is called a consuming fire (n). Christ is truly God, and he is our God and Lord; and though he is full of grace and mercy, yet he will appear in great wrath to his enemies, who will not have him to reign over them: or rather God essentially considered; whose God he is, and in what sense, and how he comes to be so; see Gill on Hebrews 8:10, what is here said of him, that he is a consuming fire, may be understood of his jealousy in matters of worship, Deuteronomy 4:23, and so carries in it a reason why he is to be served acceptably, with reverence and godly fear. God, and he only, is to be worshipped; and he is to be worshipped in a way suitable to himself; and he has the sole right of fixing the manner of worship, both as to the external and internal parts of it: under the legal dispensation, he was worshipped in a way he then pitched upon, and suitable to it; and under the Gospel dispensation he is to be worshipped in an evangelical way; and he is to have all the glory in every part of worship; and the ordinances of Gospel worship are immovable; nor are they to be altered, or others put in their room, without recurring his displeasure. Moreover, this phrase may be expressive of the preservation of his people, and of the destruction of their enemies, Deuteronomy 9:1. We commonly say, that God out of Christ is a consuming fire; meaning, that God, as an absolute God, is full of wrath and vengeance; and it is a truth, but not the truth of this text; for here it is our God, our covenant God, our God in Christ; not that he is so to the saints, or to them that are in Christ: he is indeed as a wall of fire in his providences, to protect and defend them, and as fire in his word to enlighten and warm them, to guide and direct them, but not a consuming fire to them; this he is to their enemies, who are as thorns, and briers, and stubble before him: and so the Jews interpret Deuteronomy 4:24 of a fire consuming fire (o); and observe, that Moses says, thy God, and not our God (p); but the apostle here uses the latter phrase.
