For to this end was the Gospel preached even to the dead, that they might be judged indeed as men in the flesh, but live as to God in the spirit.
But if the apostle had the same fact in view which he mentions, 1 Peter 3:19; 1 Peter 3:20, then the antedilevians are the persons intended: For this cause - that Christ is prepared to judge the quick and the dead, and to dispense righteous judgment in consequence of having afforded them every necessary advantage, was the Gospel preached by Noah to them also who are dead - the antediluvian world, then dead in trespasses and sins, and condemned to death by the righteous judgment of God; but in his great compassion he afforded them a respite, that though they were condemned as men in the flesh, (for this was their character; my Spirit will not always strive with man, forasmuch as he is FLESH, Genesis 6:3,) yet, hearing this Gospel by Noah, they may believe, and live according to God in the Spirit - live a blessed life in eternity according to the mercy of God, who sent his Spirit to strive with them. This appears to me to be the most consistent sense; especially as the apostle seems to refer to what he had said of the Spirit of Christ in Noah preaching to the spirits in prison - the rebellions that lived before the flood. See the notes on 1 Peter 3:19-20.
