Romans 6:1-7

What then shall we say? Shall we continue in sin so that grace may increase? Certainly not! How can we who died to sin live in it any longer? Or aren’t you aware that all of us who were baptized into Christ Jesus were baptized into His death? We were therefore buried with Him through baptism into death, in order that, just as Christ was raised from the dead through the glory of the Father, we too may walk in newness of life. For if we have been united with Him like this in His death, we will certainly also be united with Him in His resurrection. We know that our old self was crucified with Him so that the body of sin might be rendered powerless, that we should no longer be slaves to sin. For anyone who has died has been freed from sin.

1 Peter 3:18-22 

For Christ also suffered for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit, in whom He also went and preached to the spirits in prison who disobeyed long ago when God waited patiently in the days of Noah while the ark was being built. In the ark a few people, only eight souls, were saved through water. And this water symbolizes the baptism that now saves you also—not the removal of dirt from the body, but the pledge of a clear 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.
