1 Peter 3:18, 21-22

Christ suffered and died for sins once and for all—the innocent for the guilty —to bring you near to God by his body being put to death and by being raised to life by the Spirit.

This was a prophetic picture of the immersion that now saves you—not a bathing of the physical body but rather the response of a good conscience before God through the resurrection of Jesus Christ, who is now in heaven at the place of supreme authority next to God. The very powers of heaven, including every angel and authority, now yield in submission to him.
