From the Warfield Lectures 1981 at Princeton
“In the profound interaction between incarnation and atonement in Jesus, the blessed exchange it involved between the divine-human life of Jesus and mankind has the effect of finalising and sealing the ontological relations between every man and Jesus Christ. Thus ‘our resurrection’, as Athanasius once expressed it, ‘is stored up in the Cross.’ Through his penetration into the perverted structures of human existence he reversed the process of corruption and more than made good what had been destroyed, for he has now anchored human nature in his own crucified and risen being, freely giving it participation in the fullness of God’s grace and blessing embodied in him. Since he is the eternal Word of God by whom and through whom all things that are made are made, and in whom the whole universe of visible and invisible realities coheres and hangs together, and since in him divine and human natures are inseparably united, then the secret of every man, whether he believes or not, is bound up with Jesus for it is in him that human contingent existence has been grounded and secured.
It is precisely in Jesus, therefore, who was born of the Virgin Mary, crucified for us under Pontius Pilate and rose again in space and time, that we are to think of the whole human race, and indeed of the whole creation, as in a profound sense already redeemed, resurrected, and consecrated for the glory and worship of God. How could it be otherwise when he who became incarnate in him is the very one through whom all worlds, all ages, were made? At the same time this means, of course, that the stress upon the cross and resurrection which involves all creation, carries with it the fulfilment of salvation throughout all space and time, and thus reaches forward to the consummation of all things, in the return of Christ to make all things new, to judge the quick and the dead, and to manifest the new creation. And so, as the Creed insists, the kingdom of Jesus Christ shall have no end. The incarnation, crucifixion and resurrection of Christ, are not a transient episode but a saving fact which has been perfected once and for all, and now endures for all eternity within the one divine-human being of the Mediator.” (pp. 182-183).
