2 And wonder not that the whole world was ransomed; for it was no mere man, but the only-begotten Son of God, who died on its behalf. Moreover one man's sin, even Adam's, had power to bring death to the world; but if by the trespass of the one death reigned over the world, how shall not life much rather reign by the righteousness of the One? And if because of the tree of food they were then cast out of paradise, shall not believers now more easily enter into paradise because of the Tree of Jesus? If the first man formed out of the earth brought in universal death, shall not He who formed him out of the earth bring in eternal life, being Himself the Life? If Phinees, when he waxed zealous and slew the evil-doer, staved the wrath of God, shall not Jesus, who slew not another, but gave up Himself for a ransom, put away the wrath which is against mankind?
