As Jesus was walking beside the Sea of Galilee, he saw two brothers, Simon called Peter and his brother Andrew. They were casting a net into the lake, for they were fishermen. ‘Come, follow me,’ Jesus said, ‘and I will send you out to fish for people.’ Going on from there, he saw two other brothers, James son of Zebedee and his brother John. They were in a boat with their father Zebedee, preparing their nets. Jesus called them, and immediately they left the boat and their father and followed him.
Matthew 4:18-19, 21-22
Then Jesus said to his disciples, ‘Whoever wants to be my disciple must deny themselves and take up their cross and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will find it. What good will it be for someone to gain the whole world, yet forfeit their soul? Or what can anyone give in exchange for their soul? For the Son of Man is going to come in his Father’s glory with his angels, and then he will reward each person according to what they have done. ‘Truly I tell you, some who are standing here will not taste death before they see the Son of Man coming in his kingdom.’“
Matthew 16:24-28 NIVUK
