For since by man came death, by man came also the resurrection of the dead. For since by man came death - Mortality came by Adam, immortality by Christ; so sure as all have been subjected to natural death by Adam, so sure shall all be raised again by Christ Jesus. Mortality and immortality, on a general ground, are the subject of the apostle's reasoning here; and for the explanation of the transgression of Adam, and the redemption by Christ, see the notes on Romans 5:10, etc.
