Summary: Christ suffered for our sins to reconcile us with God, resurrected in spirit. He preached to spirits from Noah's time, paralleling baptism that saves us—not by physical cleansing but as a commitment to God, empowered by Christ's resurrection and heavenly reign.
Beloved: Christ suffered for sins once, the righteous for the sake of the unrighteous, that he might lead you to God.
Put to death in the flesh, he was brought to life in the Spirit.
In it he also went to preach to the spirits in prison, who had once been disobedient while God patiently waited in the days of Noah during the building of the ark, in which a few persons, eight in all, were saved through water.
This prefigured baptism, which saves you now. It is not a removal of dirt from the body but an appeal to God for a clear conscience, through the resurrection of Jesus Christ, who has gone into heaven and is at the right hand of God, with angels, authorities, and powers subject to him.
