Theme of discipleship being developed

...Jesus starts preaching

Now hearing that John had been captured he (Jesus) departed into Galilee. He left Nazareth and came to Capernaum beside the sea in the districts of Zebulon and Naphthali, so that what was spoken through the prophet Isaiah may be fulfilled. “Land of Zebulon and land of Naphthali, by the sea and beyond the Jordan, Galilee of the nations, the people sitting in darkness have seen a great light. For those sitting in a land under the shadow of death a light has sprung up." Then Jesus began to proclaim from there and to say “Repent for the kingdom of the heavens has drawn near.” 4:12-17

...Disciples called

On walking beside the sea of Galilee he (Jesus) saw two brothers, Simon called Peter and Andrew his brother. They were casting a net into the sea for they were fisherman. And he (Jesus) says to them. “Come after me and I will make you fishers of men.” And immediately leaving the nets they followed him. And going on from there he saw two other brothers, James the son of Zebedee and John his brother in the boat with Zebedee their father, mending their nets. And he called them. And they immediately left the boat and their father and followed him. 4:18-22

..Jesus preaching all over

He went about in all Galilee, teaching in their synagogues and proclaiming the gospel (good news) of the kingdom and healing every disease and every illness amongst the people. And the report of him went into all of Syria. They brought to him all those where were ill with various dieases, those who were tortured with demon possession and the lunatics and the paralysed. He healed them. Many crowds followed him from Galilee and Decapolis and Jerusalem and Judea and from beyond the Jordan. 4:23-25
