In John’s Gospel, “seeing” is closely linked with “believing”. The Greek verb pisteuō – “believe” – in various forms, appears more than 100 times in John’s Gospel. It is always as a verb. “Seeing”, “believing” and “witnessing” together are constitutive elements of discipleship. All are embodied in John the Baptist.
Now when Jesus heard that John had been arrested, he withdrew to Galilee. He left Nazareth and made his home in Capernaum by the sea, in the territory of Zebulun and Naphtali, so that what had been spoken through the prophet Isaiah might be fulfilled: “Land of Zebulun, land of Naphtali, on the road by the sea, across the Jordan, Galilee of the Gentiles—the people who sat in darkness have seen a great light, and for those who sat in the region and shadow of death light has dawned.” From that time Jesus began to proclaim, “Repent, for the kingdom of heaven has come near.”
When Jesus saw the crowds, he went up the mountain; and after he sat down, his disciples came to him. Then he began to speak, and taught them, saying:
“Blessed are the poor in spirit, for theirs is the kingdom of heaven.
“Blessed are those who mourn, for they will be comforted.
“Blessed are the meek, for they will inherit the earth.
