3. Having considered salvation, as designed for all the elect, we proceed to consider the means of their attaining it; or their being brought into a state of salvation by the second covenant, commonly called the covenant of grace. As salvation is ascribed to the grace of God; so it is an instance of condescending goodness, that our faith, relating hereunto, should be confirmed by such a dispensation, as is generally styled a covenant. Thus David, speaking concerning it, says, _He hath made with me an everlasting covenant, ordered in all things, and sure; for this is all my salvation, and all my desire_, 2 Sam. xxiii. 5. This covenant, as to what respects the parties concerned therein, and the manner in which the grace of God is displayed in it, together with the various dispensations, or administrations thereof, is particularly considered under the five following answers. The only thing, that remains to be insisted on in this, is its being called the _Second Covenant_, as opposed to the covenant of works, which is styled the _First_. The covenant of works has been considered under a foregoing answer[88]; and therefore all that I shall observe, concerning it, at present, is, that though life was promised therein, as including all those blessings, which were suited to the state of man in innocency, yet there was no promise of salvation in it, which is the restoring of forfeited blessings, or a recovery from a state of death and ruin. In this respect, the covenant of grace is opposed to it. Again, though Adam was the head of that covenant, whose obedience, or apostacy, would convey life or death to all his posterity, whom he represented, yet he stood not in the relation of a Mediator, or surety, to them, for that was inconsistent with the dispensation he was under, and is applicable to no other covenant, than that which we are considering, as thus opposed to it. Moreover, perfect obedience was demanded, as a condition of man’s attaining life, and this he was thoroughly furnished to perform; whereas, in the covenant of grace, if God should insist on our performing perfect obedience, the condition would be in its own nature impossible, and therefore we should hereby rather be excluded from, than brought into a state of salvation; and whatever obedience we are engaged to perform, as expectants of salvation, this is entirely owing to the grace of God, by which _we are what we are_, as well as attain to the blessings we hope for: Herein the covenant of works, and the covenant of grace, differ.
