6 Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life. giveth life: or, quickeneth
English Standard Version
6 who has made us competentOr sufficient to be ministers of a new covenant, not of the letter but of the Spirit. For the letter kills, but the Spirit gives life.
6 His letter authorizes us to help carry out this new plan of action. The plan wasn't written out with ink on paper, with pages and pages of legal footnotes, killing your spirit. It's written with Spirit on spirit, his life on our lives!
New King James Version
6 who also made us sufficient as ministers of the new covenant, not of the letter but of the Spirit; for the letter kills, but the Spirit gives life.
New Living Translation
6 He has enabled us to be ministers of his new covenant. This is a covenant not of written laws, but of the Spirit. The old written covenant ends in death; but under the new covenant, the Spirit gives life.
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, Ezekiel 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.
