The doctrine of the covenant of redemption Wherein is laid the foundation of all…

2. Hence you shall here find all those Absolute Promises which are upon Scripture Record, given for your comfort. It is true an Unbeliever can make no challenge of them to himself, or make a living of them: they are not a Dish that is set before every one to feed upon: but a believer may and ought to reckon ⟨p. 148⟩them to be his own, and to suck all the Marrow and Fatness out of them. And when you have well pondered of these Promises you may strengthen your Faith by arguing after this manner; viz. That although in the Covenant of Grace all these things are required of you, and they must be found in you if ever you be saved; yet in the Covenant of Redemption all this is undertaken for: for this is the proper language of these Promises. When God saith He will give you a New Heart, and put his Spirit upon you, and put his Fear into your Hearts, and you shall never depart from him, and the like; these Promises belong to some, there are they who are designed & pointed at by them, and who are they but such as are Ordained to Salvation from Eternity? and these are they who are Effectually called in Time. You may therefore upon the consideration of your vocation be assured of the Accomplishment of them in you; for though you might fail, yet God cannot.

And hence it comes to pass, that though Adam in his integrity, lost all his stock by the prevalency of a Temptation, that was too hard for him, yet a believer in the hand of the Spirit of God, notwithstanding all the frailties that attend upon him, shall never lose his little stock, but both keep and increase it. So that if, when we look upon the Condition required in the One Covenant, we lay by it, the consideration of the undertaking and Provision that is made for the performance of it in another Covenant, that may quiet and satisfy our souls in this regard, and enable us to
