Here, I. The apostle declares that our privileges by Christ under the gospel are not only as great, but greater than those enjoyed under the Mosaic law. He specifies this, that we have a promise left us of entering into his rest; that is, of entering into a covenant-relation to Christ, and a state of communion with God through Christ, and of growing up therein, till we are made perfect in glory. We have discoveries of this rest, and proposals, and the best directions how we may attain unto it. This promise of spiritual rest is a promise left us by the Lord Jesus Christ in his last will and testament, as a precious legacy. Our business is to see to it that we be the legatees, that we lay our claim to that rest and freedom from the dominion of sin, Satan, and the flesh, by which the souls of men are kept in servitude and deprived of the true rest of the soul, and may be also set free from the yoke of the law and all the toilsome ceremonies and services of it, and may enjoy peace with God in his ordinances and providences, and in our own consciences, and so have the prospect and earnest of perfect and everlasting rest in heaven.

II.He demonstrates the truth of his assertion, that we have as great advantages as they. For says he (Heb 4:2), To us was the gospel preached as well as unto them; the same gospel for substance was preached under both Testaments, though not so clearly; not in so comfortable a manner under the Old as under the New. The best privileges the ancient Jews had were their gospel privileges; the sacrifices and ceremonies of the Old Testament were the gospel of that dispensation; and, whatever was excellent in it, was the respect it had to Christ. Now, if this was their highest privilege, we are not inferior to them; for we have the gospel as well as they, and in greater purity and perspicuity than they had.

III.He again assigns the reason why so few of the ancient Jews profited by that dispensation of the gospel which they enjoyed, and that was their want of faith: The word preached did not profit them because it was not mixed with faith in those that heard him, Heb 4:2. Observe, 1. The word is preached to us that we may profit by it, that we may gain spiritual riches by it; it is a price put into our hands to get wisdom, the rich endowment of the soul. 2. There have been in all ages a great many unprofitable hearers; many who seem to deal much in sermons, in hearing the word of God, but gain nothing to their souls thereby; and those who are not gainers by hearing are great losers. 3. That which is at the bottom of all our unprofitableness under the word is our unbelief. We do not mix faith with what we hear; it is faith in the hearer that is the life of the word. Though the preacher believes the gospel, and endeavours to mix faith with his preaching, and to speak as one who has believed and so spoken, yet, if the hearers have not faith in their souls to mix with the word, they will be never the better for it. This faith must mingle with every word, and be in act and exercise while we are hearing; and, when we have heard the word, assenting to the truth of it, approving of it, accepting the mercy offered, applying the word to ourselves with suitable affections, then we shall find great profit and gain by the word preached.

IV.On these considerations the apostle grounds his repeated and earnest caution and counsel that those who enjoy the gospel should maintain a holy fear and jealousy over themselves, lest latent unbelief should rob them of the benefit of the word, and of that spiritual rest which is discovered and tendered in the gospel: Let us fear lest, a promise being left us of entering into his rest, any of you should seem to come short of it, Heb 4:1. Observe, 1. Grace and glory are attainable by all under the gospel: there is an offer, and a promise to those who shall accept the offer. 2. Those who may attain them may also fall short. Those who may attain them may also fall short. Those who might have attained salvation by faith may fall short by unbelief. 3. It is a dreadful thing so much as to seem to fall short of the gospel salvation, to seem so to themselves, to lose their comfortable hope; and to seem so to others, so losing the honour of their holy profession. But, if it be so dreadful to seem to fall short of this rest, it is much more dreadful really to fall short. Such a disappointment must be fatal. 4. One good means to prevent either our real falling short or seeming to fall short is to maintain a holy and religious fear lest we should fall short. This will make us vigilant and diligent, sincere and serious; this fear will put us upon examining our faith and exercising it; whereas presumption is the high road to ruin.

V.The apostle confirms the happiness of all those who truly believe the gospel; and this he does,

1.By asserting so positively the truth of it, from the experience of himself and others: "We, who have believed, do enter into rest, Heb 4:3. We enter into a blessed union with Christ, and into a communion with God through Christ; in this state we actually enjoy many sweet communications of pardon of sin, peace of conscience, joy in the Holy Ghost, increase of grace and earnests of glory, resting from the servitude of sin, and reposing ourselves in God till we are prepared to rest with him in heaven."

2.He illustrates and confirms it that those who believe are thus happy, and do enter into rest. (1.) From God's finishing his work of creation, and so entering into his rest (Heb 4:3, Heb 4:4), appointing our first parents to rest the seventh day, to rest in God. Now as God finished his work, and then rested from it, and acquiesced in it, so he will cause those who believe to finish their work, and then to enjoy their rest. (2.) From God's continuing the observance of the sabbath, after the fall, and the revelation of a Redeemer. They were to keep the seventh day a holy sabbath to the Lord, therein praising him who had raised them up out of nothing by creating power, and praying to him that he would create them anew by his Spirit of grace, and direct their faith to the promised Redeemer and restorer of all things, by which faith they find rest in their souls. (3.) From God's proposing Canaan as a typical rest for the Jews who believed: and as those who did believe, Caleb and Joshua, did actually enter into Canaan; so those who now believe shall enter into rest. (4.) From the certainty of another rest besides that seventh day of rest instituted and observed both before and after the fall, and besides that typical Canaan-rest which most of the Jews fell short of by unbelief; for the Psalmist has spoken of another day and another rest, whence it is evident that there is a more spiritual and excellent sabbath remaining for the people of God than that into which Joshua led the Jews (v. 6-9), and this rest remaining, [1.] A rest of grace, and comfort, and holiness, in the gospel state. This is the rest wherewith the Lord Jesus, our Joshua, causes weary souls and awakened consciences to rest, and this is the refreshing. [2.] A rest in glory, the everlasting sabbatism of heaven, which is the repose and perfection of nature and grace too, where the people of God shall enjoy the end of their faith and the object of all their desires. (5.) This is further proved from the glorious forerunners who have actually taken possession of this rest - God and Christ. It is certain that God, after the creating of the world in six days, entered into his rest; and it is certain that Christ, when he had finished the work of our redemption, entered into his rest; and these were not only examples, but earnests, that believers shall enter into their rest: He that hath entered into rest hath also ceased from his own works as God did from his, Heb 4:10. Every true believer hath ceased from his own works of righteousness, and from the burdensome works of the law, as God and Christ have ceased from their works of creation and redemption.

VI.The apostle confirms the misery of those who do not believe; they shall never enter into this spiritual rest, either of grace here or glory hereafter. This is as certain as the word and oath of God can make it. As sure as God has entered into his rest, so sure it is that obstinate unbelievers shall be excluded. As sure as the unbelieving Jews fell in the wilderness, and never reached the promised land, so sure it is that unbelievers shall fall into destruction, and never reach heaven. As sure as Joshua, the great captain of the Jews, could not give them possession of Canaan because of their unbelief, notwithstanding his eminent valour and conduct, so sure it is that even Jesus himself, and captain of our salvation, notwithstanding all that fulness of grace and strength that dwells in him, will not, cannot, give to final unbelievers either spiritual or eternal rest: it remains only for the people of God; others by their sin abandon themselves to eternal restlessness.

He limiteth a certain day - The term day signifies not only time in general, but also present time, and a particular space. Day here seems to have the same meaning as rest in some other parts of this verse. The day or time of rest relative to the ancient Jews being over and past, and a long time having elapsed between God's displeasure shown to the disobedient Jews in the wilderness and the days of David, and the true rest not having been enjoyed, God in his mercy has instituted another day - has given another dispensation of mercy and goodness by Christ Jesus; and now it may be said, as formerly, To-day, if ye will hear his voice, harden not your hearts. God speaks now as he spoke before; his voice is in the Gospel as it was in the law. Believe, love, obey, and ye shall enter into this rest.

Again he limiteth a certain day,.... Since the seventh day of the creation was a day of rest which God entered into, and not man; and since the land of Canaan was a typical rest, which the unbelieving Israelites did not enter into, because of unbelief; and yet there must be persons, and there must be a time for them to enter into the true rest which God has left a promise of; therefore he has limited, fixed, and appointed a certain day, the Gospel dispensation, for believers to enter into it:

saying in David; or by David, who was the penman of the 95th psalm, as may be learned from hence; and this is agreeably to, and confirms a rule which the Jews give, that those psalms which are without a title were written by David (g); the Spirit of God spake in him and by him, and plainly pointed out another day of rest from the above mentioned:

today, after so long a time; as two thousand five hundred years from the first seventh day to the time of Moses, and five hundred years from the times of Moses and Joshua, to his:

as it is said; the Alexandrian copy reads, "as it is before said", or, "above said", as the Vulgate Latin, and Syriac versions; that is, in Psa 95:7 before cited, Heb 3:7

today if you will hear his voice, harden not your hearts; See Gill on Heb 3:7, Heb 3:8.

(g) Aben Ezra & Kimchi Praefat. in Tillim.

Again--Anew the promise recurs. Translate as the Greek order is, "He limited a certain day, 'To-day.'" Here Paul interrupts the quotation by, "In (the Psalm of) David saying after so long a time (after five hundred years' possession of Canaan)," and resumes it by, "as it has been said before (so the Greek oldest manuscript, before, namely, Heb 3:7, Heb 3:15), To-day if ye hear His voice," &c.
