"3. God’s Design and Result Exactly Co-Extensive.
There is no safer clue for the student 
through this perplexed subject, than, to take this proposition; which, to every 
Calvinist, is nearly as indisputable as a truism; Christ’s design in His 
vicarious work was to effectuate exactly what it does effectuate, and all that 
it effectuates, in its subsequent proclamation. This is but saying that Christ’s 
purpose is unchangeable and omnipotent. Now, what does it actually effectuate? 'We know only in part,' but so much is certain.
(a.) The purchase of the full and assured 
redemption of all the elect, or of all believers.
(b.) A reprieve of doom for every sinner 
of Adam’s race who does not die at his birth (For these we believe it has 
purchased heaven). And this reprieve gains for all, many substantial, though 
temporal benefits, such as unbelievers, of all men, will be the last to account 
no benefits. Among these are postponement of death and perdition, secular well 
being, and the bounties of life.
(c.) A manifestation of God’s mercy to 
many of the non-elect, to all those, namely, who live under the Gospel, in 
sincere offers of a salvation on terms of faith. And a sincere offer is a real 
and not a delusive benefaction; because it is only the recipient's contumacy 
which disappoints it.
(d.) A justly enhanced condemnation of 
those who reject the Gospel, and thereby a clearer display of God’s 
righteousness and reasonableness in condemning, to all the worlds.
(e.) A disclosure of the infinite 
tenderness and glory of God’s compassion, with purity, truth and justice, to all 
rational creatures.
Had there been no mediation of Christ, we 
have not a particle of reason to suppose that the doom of our sinning race would 
have been delayed one hour longer than that of the fallen angels. Hence, it 
follows, that it is Christ who procures for non-elect sinners all that they 
temporarily enjoy, which is more than their personal deserts, including the 
sincere offer of mercy. In view of this fact, the scorn which Dr. William 
Cunningham heaps on the distinction of a special, and general design in Christ’s 
satisfaction, is thoroughly shortsighted. All wise beings (unless God be the 
exception), at times frame their plans so as to secure a combination of results 
from the same means. This is the very way they display their ability and wisdom. 
Why should God be supposed incapable of this wise and fruitful acting? I repeat, 
the design of Christ’s sacrifice must have been to effectuate just what it does 
effectuate. And we see, that, along with the actual redemption of the elect, it 
works out several other subordinate ends. There is then a sense, in which Christ 'died for' all those ends, and for the persons affected by them" (R.L. Dabney, Lectures on Systematic Theology, pp. 528-529).
