In those days John the Baptist came, preaching in the Desert of Judea and saying, "Repent, for the kingdom of heaven is near." This is he who was spoken of through the prophet Isaiah: "A voice of one calling in the desert, 'Prepare the way for the Lord, make straight paths for him.'"
John's clothes were made of camel's hair, and he had a leather belt around his waist. His food was locusts and wild honey. People went out to him from Jerusalem and all Judea and the whole region of the Jordan. Confessing their sins, they were baptized by him in the Jordan River.
But when he saw many of the Pharisees and Sadducees coming to where he was baptizing, he said to them: "You brood of vipers! Who warned you to flee from the coming wrath? Produce fruit in keeping with repentance. And do not think you can say to yourselves, 'We have Abraham as our father.' I tell you that out of these stones God can raise up children for Abraham.
Matthew 3:1-9
Produce fruit in keeping with repentance. And do not begin to say to yourselves, 'We have Abraham as our father.' For I tell you that out of these stones God can raise up children for Abraham. The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire."
"What should we do then?" the crowd asked.
John answered, "The man with two tunics should share with him who has none, and the one who has food should do the same."
Tax collectors also came to be baptized. "Teacher," they asked, "what should we do?"
"Don't collect any more than you are required to," he told them.
Then some soldiers asked him, "And what should we do?"
He replied, "Don't extort money and don't accuse people falsely - be content with your pay."
The people were waiting expectantly and were all wondering in their hearts if John might possibly be the Christ.
John answered them all, "I baptize you with water. But one more powerful than I will come, the thongs of whose sandals I am not worthy to untie. He will baptize you with the Holy Spirit and with fire.
