This document describes a Halloween activity called "Peter Pumpkin" that uses a carved pumpkin to teach children about sin and forgiveness through Jesus. It involves carving a face on the pumpkin and telling a story where pieces of the pumpkin's face are removed to represent sins committed by the character Peter during his day. The pieces are put back in when the children are taught that Jesus forgives sins. A cross is then carved into the pumpkin to represent that with Jesus, the light will not go out.
