Each of the Gospels has its own way of telling how Jesus called his disciples. In today’s reading from St. Luke’s Gospel we can see how Jesus used a miraculous catch of fish as the opportunity to call the first of those who came to be his disciples.
At some point early in his ministry Jesus established Capernaum as his home, on the NW corner of the Sea of Galilee, also called the Lake of Genneseret.
Jesus had become a familiar sight as he walked along the shore of that inland sea. Because of this Peter and those fishing with him could feel comfortable with him on that day when Jesus got into one of their boats and asked them to put out into deep water and let down their nets.
