1 Peter 3:18-22

For Christ also suffered for sins once for all, the righteous for the unrighteous, that he might bring you to God. He was put to death in the flesh but made alive by the Spirit, in which he also went and made proclamation to the spirits in prison who in the past were disobedient, when God patiently waited in the days of Noah while the ark was being prepared. In it a few — that is, eight people  — were saved through water. Baptism, which corresponds to this, now saves you (not as the removal of dirt from the body, but the pledge of a good conscience toward God) 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.
