God has Spoken Through His Son
The writer of Hebrews said, "God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets, hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds; who being the brightness of his glory, and the express image of his person, when he had by himself purged our sins, sat down on the right hand of the Majesty on high." (Hebrews 1:1-3).
Matthew Henry states in his commentary, "This epistle shows Christ as the end, foundation, body, and truth of the figures of the law, which of themselves were no virtue for the soul. The great truth set forth in this epistle is that Jesus of Nazareth is the true God. The unconverted Jews used many arguments to draw their converted brethren from the Christian faith. They represented the law of Moses as superior to the Christian dispensation, and spoke against every thing connected with the Saviour. The apostle, therefore, shows the superiority of Jesus of Nazareth, as the Son of God, and the benefits from his sufferings and death as the sacrifice for sin, so that the Christian religion is much more excellent and perfect than that of Moses. And the principal design seems to be, to bring the converted Hebrews forward in the knowledge of the gospel, and thus to establish them in the Christian faith, and to prevent their turning from it, against which they are earnestly warned.
"But while it contains many things suitable to the Hebrews of early times, it also contains many which can never cease to interest the church of God; for the knowledge of Jesus Christ is the very marrow and kernel of all the Scriptures. The ceremonial law is full of Christ, and all the gospel is full of Christ; the blessed lines of both Testaments meet in Him; and how they both agree and sweetly unite in Jesus Christ, is the chief object of the epistle to the Hebrews to discover.
"God spake to his ancient people at sundry times, through successive generations, and in divers manners, as he thought proper; sometimes by personal directions, sometimes by dreams, sometimes by visions, sometimes by Divine influences on the minds of the prophets. The gospel revelation is excellent above the former; in that it is a revelation which God has made by his Son. In beholding the power, wisdom, and goodness of the Lord Jesus Christ, we behold the power, wisdom, and goodness of the Father; the fulness of the Godhead dwells, not typically, or in a figure, but really, in him.
"When, on the fall of man, the world was breaking to pieces under the wrath and curse of God, the Son of God, undertaking the work of redemption, sustained it by his almighty power and goodness. From the glory of the person and office of Christ, we proceed to the glory of his grace. The glory of His person and nature, gave to his sufferings such merit as was a full satisfaction to the honour of God, who suffered an infinite injury and affront by the sins of men. We never can be thankful enough that God has in so many ways, and with such increasing clearness, spoken to us fallen sinners concerning salvation. That he should by himself cleanse us from our sins is a wonder of love beyond our utmost powers of admiration, gratitude, and praise."
