We were under the old covenant, and our first father and federal head, Adam, had broken that covenant, and we were ruined by his fatal breach. The substance of the old covenant was on this wise,—”If thou wilt keep my command thou shalt live, and thy posterity shall live; but if thou shalt eat of the tree which I have forbidden thee, dying, thou shalt die, and all thy posterity in thee.”
This is where we were found, broken in pieces, sore wounded, and even slain by the tremendous fall which destroyed both our Paradise and ourselves. We died in Adam as to spiritual life, and our death revealed itself in an inward tendency to evil which reigned in our members. We were like Ezekiel’s deserted infant unswaddled and unwashed, left in our pollution to die; but the Son of God passed by and saw us in the greatness of our ruin.
In his wondrous love our Lord Jesus put us under a new covenant, a covenant of which he became the second Adam, a covenant which ran on this wise,—”If thou shalt render perfect obedience and vindicate my justice, then those who are in thee shall not perish, but they shall live because thou livest.” Now, our Lord Jesus, our Surety and Covenant Head, has fulfilled his portion of the covenant engagement, and the compact stands as a bond of pure promise without condition or risk.
Those who are participants in that covenant cannot invalidate it, for it never did depend upon them, but only upon him who was and is their federal head and representative before God. Of Jesus the demand was made and he met it. By him man’s side of the covenant was undertaken and fulfilled, and now no condition remains; it is solely made up of promises which are unconditional and sure to all the seed.
To-day believers are not under the covenant of “If thou doest this thou shalt live,” but under that new covenant which says, “Their sins and their iniquities will I remember no more.” It is not now “Do and live,” but “Live and do;” we think not of merit and reward, but of free grace producing holy practice as the result of gratitude. What law could not do, grace has accomplished.
