Jesus said that "I am the light of the world" and through him, we are baptised into the family of God. So after baptism, a lit candle is given to the parents of the baptised child to reflect this hope that the child will live as a light of Jesus.
Some of the children shared pictures of their baptism with the class, then we watched a video of baptism taking place and completed this class collage that reminds us of Jesus being the light of the world.
