Synopsis of the Books of the Bible, by John Nelson Darby, [1857-62], at sacred-texts.com
Chapter 8 in this respect is simple and clear; the last Verses only give room for a few remarks.
The sum of the doctrine we have been considering is, that we have a High Priest who is seated on the throne of the Majesty in the heavens, a Minister of the heavenly sanctuary which is not made with hands. As such, He must have an offering to present there. Jesus, were He on earth, would not be a Priest; there were priests on earth according to the law, in which all things were but figures of the heavenly things; as Moses was told to make all according to the pattern that was shewn him in the mount. But the ministry of Jesus is more excellent, because He is the Mediator of a better covenant, spoken of in Jeremiah 31, which is here quoted; a clear and simple proof that the first covenant was not to continue.
We again find here that particular development of the truth which was called for by the character of the persons to whom this letter was addressed.
The first covenant was made with Israel; the second must be so likewise, according to the prophecy of Jeremiah. The epistle however in this passage only makes use of the fact that there was to be a second covenant, in order to demonstrate that the first was to last no longer. It had grown old, and was to vanish away. He recites the terms of the new covenant. We shall find that he makes use of it afterwards. In that which follows, he contrasts the services that belonged to the first with the perfect work on which Christianity is founded. Thus the extent and the value of the work of Christ are introduced.
Although there is no difficulty here, it is important to have light with regard to these two covenants, because some have very vague ideas on this point, and many souls, putting themselves under covenants, that is, in relationship with God under conditions in which He has not placed them lose their simplicity, and do not hold fast grace and the fullness of the work of Christ, and the position He has acquired for them in heaven.
A covenant is a principle of relationship with God on the earth conditions established by God under which man is to live with Him. The word may perhaps be used figuratively, or by accommodation. It is applied to details of the relationship of God with Israel, and so to Abraham (Gen.15), and like cases; but, strictly speaking, there are but two covenants, in which God has dealt with man on earth, or will the old and the new. The old was established at Sinai. The new covenant is made also with the two houses of Israel. [See Note #15]
The gospel is not a covenant, but the revelation of the salvation of God. It proclaims the, great salvation of God. We enjoy indeed all the essential privileges of the new covenant, its foundation being laid on God's part in the blood of Christ, but we do so in spirit, not according to the letter.
The new covenant will be established formally with Israel in the millennium. Meanwhile the old covenant is judged by the fact that there is a new one.
We have also, at the end of the epistle, the expression " the blood of the everlasting covenant." " Covenant" he uses I doubt not (as the word "law" also is used), because it was commonly employed as the condition of relationship with God, and " eternal " is characteristic of the Hebrews. There have been, and will be, covenants in time and for the earth; but we have eternal conditions of relationship with God, of which the blood of Christ is the expression and security, founded in everlasting grace, and righteousness as well as grace, by that precious blood, in which all the character and all the purpose of God has been made good and glorified, as well as our sins been put away.
