3:6 {2} Who also hath made us able ministers of the new testament; not of the {f} letter, but of the spirit: for the letter killeth, but the spirit giveth life.
(2) He amplifies his ministry and his fellows: that is to say, the ministry of the Gospel comparing it with the ministry of the Law, which he considers in the person of Moses, by whom the Law was given: against whom he sets Christ the author of the Gospel. Now this comparison is taken from the very substance of the ministry. The Law is as it were a writing in itself, dead, and without efficacy: but the Gospel, and new Covenant, as it were the very power of God itself, in renewing, justifying, and saving men. The Law offers death, accusing all men of unrighteousness: the Gospel offers and gives righteousness and life. The administration of the Law served for a time to the promise: the Gospel remains to the end of the world. Therefore what is the glory of the Law in comparison of the majesty of the Gospel?
(f) Not of the Law but of the Gospel.
3:6 Who also hath made us able ministers. God gave Paul and his fellow-ministers their sufficiency (2Co 3:5), who had made them able ministers of the gospel.
Of the new testament. The New Covenant, the Covenant of Christ. This is here contrasted with the Old Covenant, the Jewish. One is the Law; the other the Gospel. Compare Heb 8:7-13.
Not of the letter, but of the spirit. The first, the law, was written (by letters written and engraved on stones, hence of the letter ); the gospel is the dispensation of the Spirit.
The letter killeth. The law. It condemns all who do not obey its commands, but could make no man perfect. The law places under the sentence of death. See notes on Ro 7:9,10.
The spirit giveth life. The gospel bestows eternal life.
3:6 Who also hath made us able ministers of the new covenant - Of the new, evangelical dispensation. Not of the law, fitly called the letter, from God's literally writing it on the two tables. But of the Spirit - Of the gospel dispensation, which is written on the tables of our hearts by the Spirit. For the letter - The law, the Mosaic dispensation. Killeth - Seals in death those who still cleave to it. But the Spirit - The gospel, conveying the Spirit to those who receive it. Giveth life - Both spiritual and eternal: yea, if we adhere to the literal sense even of the moral law, if we regard only the precept and the sanction as they stand in themselves, not as they lead us to Christ, they are doubtless a killing ordinance, and bind us down under the sentence of death.
3:1-11 Even the appearance of self-praise and courting human applause, is painful to the humble and spiritual mind. Nothing is more delightful to faithful ministers, or more to their praise, than the success of their ministry, as shown in the spirits and lives of those among whom they labour. The law of Christ was written in their hearts, and the love of Christ shed abroad there. Nor was it written in tables of stone, as the law of God given to Moses, but on the fleshy (not fleshly, as fleshliness denotes sensuality) tables of the heart, Eze 36:26. Their hearts were humbled and softened to receive this impression, by the new-creating power of the Holy Spirit. He ascribes all the glory to God. And remember, as our whole dependence is upon the Lord, so the whole glory belongs to him alone. The letter killeth: the letter of the law is the ministration of death; and if we rest only in the letter of the gospel, we shall not be the better for so doing: but the Holy Spirit gives life spiritual, and life eternal. The Old Testament dispensation was the ministration of death, but the New Testament of life. The law made known sin, and the wrath and curse of God; it showed us a God above us, and a God against us; but the gospel makes known grace, and Emmanuel, God with us. Therein the righteousness of God by faith is revealed; and this shows us that the just shall live by his faith; this makes known the grace and mercy of God through Jesus Christ, for obtaining the forgiveness of sins and eternal life. The gospel so much exceeds the law in glory, that it eclipses the glory of the legal dispensation. But even the New Testament will be a killing letter, if shown as a mere system or form, and without dependence on God the Holy Spirit, to give it a quickening power.
