Jesus Christ the same, etc. The only way by which we can persevere in the right faith is to hold to the foundation, and not in the smallest degree to depart from it; for he who holds not to Christ knows nothing but mere vanity, though he may comprehend heaven and earth; for in Christ are included all the treasures of celestial wisdom. This then is a remarkable passage, from which we learn that there is no other way of being truly wise than by fixing all our thoughts on Christ alone. Now as he is dealing with the Jews, he teaches them that Christ had ever possessed the same sovereignty which he holds at this day; The same, he says, yesterday, and today, and forever. By which words he intimates that Christ, who was then made known in the world, had reigned from the beginning of the world, and that it is not possible to advance farther when we come to him. Yesterday then comprehends the whole time of the Old Testament; and that no one might expect a sudden change after a short time, as the promulgation of the Gospel was then but recent, he declares that Christ had been lately revealed for this very end, that the knowledge of him might continue the same for ever. It hence appears that the Apostle is not speaking of the eternal existence of Christ, but of that knowledge of him which was possessed by the godly in all ages, and was the perpetual foundation of the Church. It is indeed certain that Christ existed before he manifested his power; but the question is, what is the subject of the Apostle. Then I say he refers to quality, so to speak, and not to essence; for it is not the question, whether he was from eternity with the Father, but what was the knowledge which men had of him. But the manifestation of Christ as to its external form and appearance, was indeed different under the Law from what it is now; yet there is no reason why the Apostle could not say truly and properly that Christ, as regarded by the faithful, is always the same.

Jesus Christ the same yesterday - As this stands in our common translation, it conveys an idea which is not in the original. It would seem to mean that Jesus Christ, the unchangeable Saviour, was the end or aim of the conduct of those referred to, or that they lived to imitate and glorify him. But this is by no means the meaning in the original. There it stands as an absolute proposition, that "Jesus Christ is the same yesterday, today, and forever;" that is, that he is unchangeable. The evident design of this independent proposition here is, to encourage them to persevere by showing that their Saviour was always the same; that he who had sustained his people in former times, was the same still, and would be the same forever. The argument here, therefore, for perseverance is founded on the "immutability" of the Redeemer. If he were fickle, vacillating, changing in his character and plans; if today he aids his people, and tomorrow will forsake them; if at one time he loves the virtuous, and at another equally loves the vicious; if he formed a plan yesterday which he has abandoned today; or if he is ever to be a different being from what he is now, there would be no encouragement to effort. Who would know what to depend on? Who would know what to expect tomorrow? For who could have any certainty that he could ever please a capricious or a vacillating being? Who could know how to shape his conduct if the principles of the divine administration were not always the same? At the same time, also, that this passage furnishes the strongest argument for fidelity and perseverance, it is an irrefragable proof of the divinity of the Saviour. It asserts immutability - sameness in the past, the present, and to all eternity but of whom can this be affirmed but God? It would not be possible to conceive of a declaration which would more strongly assert immutability than this.

Jesus Christ the same yesterday - In all past times there was no way to the holiest but through the blood of Jesus, either actually shed, or significantly typified. To-day - he is the lamb newly slain, and continues to appear in the presence of God for us. For ever - to the conclusion of time, he will be the way, the truth, and the life, none coming to the Father but through him; and throughout eternity, εις τους αιωνας, it will appear that all glorified human spirits owe their salvation to his infinite merit. This Jesus was thus witnessed of by your guides, who are already departed to glory. Remember Him; remember them; and take heed to yourselves.

(5) Jesus Christ the same yesterday, and to day, and for ever.
(5) He repeats the sum of the doctrine, that is, the only ground of all precepts of conduct, and that is this: That we ought to quiet and content ourselves in Christ only: for there has never been any man saved without the knowledge of him, neither is there today, nor shall there be ever.

Jesus Christ, the same yesterday, and today, and for ever. Who is the substance of the word spoken by the above mentioned rulers, the author and object of their faith, and the end in which their conversation terminated. These words may be expressive of the duration of Christ: he was "yesterday", which does not design the day immediately foregoing, nor some little time past, but ancient times, formerly, of old; and though it does not extend to eternity, which is true of Christ, yet may be carried further than to the days of his flesh here on earth, even to the whole Old Testament dispensation; yea, to the beginning of the world, when he existed not only as the eternal Word, the everlasting "I am", but as the Saviour and Redeemer of his people; during which dispensation he frequently appeared in an human form, and was the sum of all promises and prophecies, and the substance of all types and shadows, and the spiritual food of his people: and he is "today" under the Gospel dispensation; in his person as God-man, and in his offices as prophet, priest, and King: and will be so "for ever": he will never die more; his kingdom is an everlasting kingdom, and his priesthood an unchangeable one. Moreover, these words may regard the immutability of Christ; who is unchangeable in his person, perfections, and essence, as God; and in his love to his people; and in the fulness of his grace, and in the efficacy of his blood, and in the virtue of his sacrifice and righteousness: it may be observed, that , translated "the same", answers to "he", a name of God, Psalm 102:27 and which is used in Jewish writings (x) for a name of God; and so it is among the Turks (y): and it is expressive of his eternity, immutability, and independence; and well agrees with Christ, who is God over all, blessed for ever.

This verse is not, as some read it, in apposition with "the end of their conversation" (Hebrews 13:7), but forms the transition. "Jesus Christ, yesterday and to-day (is) the same, and (shall be the same) unto the ages (that is, unto all ages)." The Jesus Christ (the full name being given, to mark with affectionate solemnity both His person and His office) who supported your spiritual rulers through life even unto their end "yesterday" (in times past), being at once "the Author and the Finisher of their faith" (Hebrews 12:2), remains still the same Jesus Christ "to-day," ready to help you also, if like them you walk by "faith" in Him. Compare "this same Jesus," Acts 1:11. He who yesterday (proverbial for the past time) suffered and died, is to-day in glory (Revelation 1:18). "As night comes between yesterday and to-day, and yet night itself is swallowed up by yesterday and to-day, so the "suffering" did not so interrupt the glory of Jesus Christ which was of yesterday, and that which is to-day, as not to continue to be the same. He is the same yesterday, before He came into the world, and to-day, in heaven. Yesterday in the time of our predecessors, and to-day in our age" [BENGEL]. So the doctrine is the same, not variable: this verse thus forms the transition between Hebrews 13:7 and Hebrews 13:9. He is always "the same" (Hebrews 1:12). The same in the Old and in the New Testament.

Men may die; but Jesus Christ, yea, and his gospel, is the same from everlasting to everlasting.
