In reading 2 from 1 Peter 2, Peter wrote: Christ himself bore our sins in his body upon the cross, so that, free from sin, we might live for righteousness. By his wounds you have been healed. For you had gone astray like sheep, but you have now returned to the shepherd and guardian of your souls. This is what Christianity is all about and Peter fully realized it then. If we realize it now, it's time for us to become full-fledged Christians.
