Darkness and light are two important themes throughout John’s Gospel. From the very first chapter until the last, John talks a lot about darkness and light. In the beginning was the Word and the Word was with God and the Word was God. All things came into being through him, and what came into being from him was life, and the life was the light of all people. The light shines in the darkness, and the darkness does not overcome it. The Gospel goes on to tell us that John the Baptist was sent as a witness to the light.
