From these things it will inevitably follow, that however Christ in some sense may be said to die for all, and to redeem all visible Christians, yea, the whole world, by his death; yet there must be something particular in the design of his death, with respect to such as he intended should actually be saved thereby. As appears by what has been now shown, God has the actual salvation or redemption of a certain number in his proper absolute design, and of a certain number only; and therefore such a design only can be prosecuted in any thing God does, in order to the salvation of men. God pursues a proper design of the salvation of the elect in giving Christ to die, and prosecutes such a design with respect to no other, most strictly speaking; for it is impossible, that God should prosecute any other design than only such as he has: he certainly does not, in the highest propriety and strictness of speech, pursue a design that he has not. And, indeed, such a particularity and limitation of redemption will as infallibly follow, from the doctrine of God’s foreknowledge, as from that of the decree. For it is as impossible, in strictness of speech, that God should prosecute a design, or aim at a thing, which he at the same time most perfectly knows will not be accomplished, as that he should use endeavours for that which is beside his decree.

This is certain, that God did not intend to save those by the death of Christ, that he certainly knew from all eternity he should not save by his death. Wherefore, it is certain that if he intended to save any by the death of Christ, he intended to save those whom he certainly knew he should save by his death. This is all that was ever pleaded for. (Vol 13, Yale UP, 1994, 211).

“Now can we suppose that Christ came down from heaven and went through all this upon uncertainties, not knowing what purchase he should get, how great or how small? Did he die only upon probabilities, without absolute certainty who, or how many, or whether any should be redeemed by what he did and suffered?“ (ibid, 212).
