THE NEW COVENANT
15. Of ourselves--in our own wisdom and strength--we cannot effect, discover nor teach any counsel or help for man, whether for ourselves or others. Any good work we perform among you, any doctrine we write upon your heart that is God's own work. He puts into our heart and mouth what we should say, and impresses it upon your heart through the Holy Spirit. Therefore, we cannot ascribe to ourselves any honor therein, cannot seek our own glory as the self-instructed and proud spirits do; we must give to God alone the honor, and must glory in the fact that by his grace and power he works in you unto Salvation, through the office committed unto us.
16. Now, Paul's thought here is that nothing should be taught and practiced in the Church but what is unquestionably God's Word. It will not do to introduce or perform anything whatever upon the strength of man's judgment. Man's achievements, man's reasoning and power, are of no avail save in so far as they come from God. As Peter says in his first epistle (ch. 4:11): "If any man speaketh, speaking as it were oracles of God; if any man ministereth, ministering as of the strength which God supplieth." In short, let him who would be wise, who would boast of great skill, talents and power, confine himself to things other than spiritual; with respect to spiritual matters, let him keep his place and refrain from boasting and pretense. For it is of no moment that men observe your greatness and ability; the important thing is that poor souls may rest assured of being presented with God's Word and works, whereby they may be saved.
"Who also made us sufficient as ministers of a new covenant; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life."
17. Paul here proceeds to exalt the office and power of the Gospel over the glorying of the false apostles, and to elevate the power of the Word above that of all other doctrine, even of the Law of God. Truly we are not sufficient of ourselves and have nothing to boast of so far as human activity is considered. For that is without merit or power, however strenuous the effort may be to fulfil God's Law. We have, however, something infinitely better to boast of, something not grounded in our own activity: by God we have been made sufficient for a noble ministry, termed the ministry "of a New Covenant." This ministry is not only exalted far above any teaching to be evolved by human wisdom, skill and power, but is more glorious than the ministry termed the "Old Covenant," which in time past was delivered to the Jews through Moses. While this ministry clings, in common with other doctrine, to the Word given by revelation, it is the agency whereby the Holy Spirit works in the heart. Therefore, Paul says it is not a ministration of the letter, but "of the spirit."
