As he walked by the Sea of Galilee, he saw two brothers, Simon who is called Peter and Andrew his brother, casting a net into the sea; for they were fishermen. And he said to them, “Follow me, and I will make you fishers of men.” Immediately they left their nets and 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. Immediately they left the boat and their father, and followed him. And he went about all Galilee, teaching in their synagogues and preaching the gospel of the kingdom.
St. Nikolai Velimirovic wrote about the above Gospel:
“We are presented with two examples of obedience: that of the fish and that of the apostles, and it is clear which is the more touching. The fish obey the Lord’s command and unhesitatingly place their lives at His feet. The Lord had created them to serve men’s bodily needs. But see how the fish are able to fulfill a spiritual need of men. To those who had fled from God, to rebellious and disobedient men, they served as an example of obedience to their Creator. In very truth, these fish could not have been more greatly glorified had they been left to live and swim in the Lake of Gennesaret. They redeemed their lives with great honor by serving in the plan of the Lord, the Redeemer, as an example and reprimand to disobedient men. The Lord’s inexpressible mercy is evident in this: the Lord uses all His creatures to bring man back to the path that he has lost, to arouse him, sober him and raise him once more to his primal dignity.” (Homilies: Volume 2, pg. 188)
