1 Peter 2:24-25 (NIV)
24He himself bore our sins in his body on the tree, so that we might die to sins and live for righteousness; by his wounds you have been healed.
25For you were like sheep going astray, but now you have returned to the Shepherd and Overseer of your souls
1 Peter 3:18-22 (NIV)
18For Christ died 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 by the Spirit,
19through whom also he went and preached to the spirits in prison
20who disobeyed 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,
21and this water symbolizes baptism that now saves you also–not the removal of dirt from the body but the pledge of a good conscience toward God. It saves you by the resurrection of Jesus Christ,
22who has gone into heaven and is at God’s right hand–with angels, authorities and powers in submission to him.
