Mark 1:16 In-Context

14 Now after John was arrested, Jesus came to Galilee, proclaiming the good news of God,
15 and saying, "The time is fulfilled, and the kingdom of God has come near; repent, and believe in the good news."
16 As Jesus passed along the Sea of Galilee, he saw Simon and his brother Andrew casting a net into the sea—for they were fishermen.
17 And Jesus said to them, "Follow me and I will make you fish for people."
18 And immediately they left their nets and followed him.
