In the Book of Revelation John begins by writing to the seven Churches that were near Patmos, the penal island on which John was incarcerated. He writes to these living communities with a word from Jesus, a word that affirms them and also a word that challenges them. These churches or Christian communities are referred to by John as the 7 lampstands among whom Jesus walks. As lampstands they are to give light to the culture around them otherwise their light will be extinguished. Their light will burn out if they are not faithful to Jesus the faithful witness.
