“After being made alive, he went and made proclamation to the imprisoned spirits—to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built. In it only a few people, eight in all, were saved through water, and this water symbolizes baptism that now saves you also—not the removal of dirt from the body but the pledge of a clear conscience toward God. It saves you by the resurrection of Jesus Christ who has gone into heaven and is at God’s right hand—“
1 Peter 3:18-22
I think Peter felt as he was writing this, that he also had once barely made it. That he once, long ago, stood breathless and drenched on the deck of a ship looking out over his conscience now clear as glass, thanking his savior for setting him free.
