John the Baptist wore clothes made of camel’s hair and a leather belt and he ate locusts and wild honey. The Word of God came to John the Baptist so he came into the country around Jordan and started to preach about the baptism of repentance for the remission of sins.

The people of Jerusalem and all Judæa and all around Jordan were baptized by John in the Jordan river and they confessed their sins. This is why he became known as John the Baptist.

When John saw many of the Pharisees and Sadducees (The religious leaders of the time) come to his baptism, he asked them, O generation of vipers, who warned you to run from the wrath to come? Make your actions worthy of repentance and don’t think to yourselves; We have Abraham as our father because I tell you, God is able to make children of Abraham out of these stones. Know also that the axe cuts at the root of the trees: every tree that doesn’t produce good fruit is cut down and thrown into the fire.

See John the Baptist as well as all of the prophets were aware that the religious leaders were hypocrites and were not right in the eyes of the Lord.

The people asked John how they should live and John answered, If you have two coats, give one to someone who has none and if you have food, do the same. Then tax collectors came to be baptized too and asked John how they should live. John told them, Collect no more than what you’re ordered to. And the soldiers asked, And what should we do? John answered them, Do violence to nobody, don’t accuse anyone falsely, and be content with your wages.

The Jewish Religious leaders sent priests and Levites from Jerusalem to ask John who he was, and the people wondered if he was the Christ or not. John declared, I am not the Christ. They asked, Then are you Elijah? John said, I am not. So they asked him, Who do you say you are, so we can tell the people that sent us? John said, I am the voice of one crying in the wilderness. Make straight the way of the Lord, as the prophet Isaiah said.

John preached many other things to the people. He also criticized king Herod because Herod married Herodias, who was Herod’s brother Philip’s wife, and for all the other evil things he had done.

Then Jesus came from Galilee to Jordan to be baptized of John. When John saw Jesus he said, Behold the Lamb of God, who takes away the sin of the world. This is who I spoke of when I said, After me comes a man who is preferred before me: because He was before me. I didn’t know Him, except that He would be made known to Israel, so I have come baptizing with water.

John said to Jesus, I need to be baptized of you, and you come to me? Jesus answered, Allow it to be. We must fulfill all righteousness.

JOHN THE BAPTIST TOLD JESUS AT THE BAPTISM OF JESUS THAT IT WAS JESUS THAT SHOULD BE BAPTIZING JOHN. JESUS TOLD JOHN THAT THEY NEEDED TO FULFILL ALL RIGHTEOUSNESS. MATTHEW 3:13-15
 

MOST DO NOT UNDERSTAND WHAT JESUS MEANT WHEN HE SAID THAT HE AND JOHN WERE TO "FULFILL ALL RIGHTEOUSNESS" ... HE WAS REFERRING TO SPIRITUAL FULFILLING OF A HOLY DAY KNOWN AS DAY OF ATONEMENT DESCRIBED IN (LEVITICUS 16:21-31)
