"For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit." (1 Peter 3:18)
Humanity must be resurrected. This is not an incidental "religious" issue: "But if there be no resurrection of the dead, then is Christ not risen"(1 Corinthians 15:13).
