“Christ became incarnate, or, which is the same thing, became man, to put himself in a capacity for working out our redemption. For though Christ, as God, was infinitely sufficient for the work, yet to his being in an immediate capacity for it, it was needful that he should not only be God, but man. If Christ had remained only in the divine nature, he would not have been in a capacity to have purchased our salvation; not from any imperfection of the divine nature, but by reason of its absolute and infinite perfection: for Christ, merely as God, was not capable either of that obedience or suffering that was needful. The divine nature is not capable of suffering; for it is infinitely above all suffering. Neither is it capable of obedience to that law which was given to man. It is as impossible that one who is only God, should obey the law that was given to man, as it is that he should suffer man’s punishment. And it was necessary not only that Christ should take upon him a created nature, but that he should take upon him our nature…
“Christ’s incarnation was a greater and more wonderful thing than ever had yet come to pass. The creation of the world was a very great thing, but not so great as the incarnation of Christ. It was a great thing for God to make the creature, but not so great as for the Creator himself to become a creature. We have spoken of many great things that were accomplished between the fall of man and the incarnation of Christ: but God becoming man was greater than all. Then the greatest person was born that ever was or ever will be.”
Jonathan Edwards
