First Reading: Jonah 3:1–5, 10
The word of the LORD came to Jonah a second time, saying, 2Get up, go to Nineveh, that great city, and proclaim to it the message that I tell you. 3So Jonah set out and went to Nineveh, according to the word of the LORD. Now Nineveh was an exceedingly large city, a three days' walk across. 4Jonah began to go into the city, going a day's walk. And he cried out, "Forty days more, and Nineveh shall be overthrown!" 5And the people of Nineveh believed God; they proclaimed a fast, and everyone, great and small, put on sackcloth.
10When God saw what they did, how they turned from their evil ways, God changed his mind about the calamity that he had said he would bring upon them; and he did not do it.
Second Reading: 1 Corinthians 7:29–31
29I mean, brothers and sisters, the appointed time has grown short; from now on, let even those who have wives be as though they had none, 30and those who mourn as though they were not mourning, and those who rejoice as though they were not rejoicing, and those who buy as though they had no possessions, 31and those who deal with the world as though they had no dealings with it. For the present form of this world is passing away.
Gospel: Mark 1:14–20
14Now after John was arrested, Jesus came to Galilee, proclaiming the good news of God, 15and saying, "The time is fulfilled, and the kingdom of God has come near, repent, and believe in the good news."
16As Jesus passed along the Sea of Galilee, he saw Simon and his brother Andrew casting a net into the sea — for they were fishermen. 17And Jesus said to them, "Follow me and I will make you fish for people." 18And immediately they left their nets and followed him. 19As he went a little farther, he saw James son of Zebedee and his brother John, who were in their boat mending the nets. 20Immediately he called them; and they left their father Zebedee in the boat with the hired men, and followed him.
