"Behold the Lamb of God, which taketh away the sin of the world." — John 1:29 (KJV)
The short answer
John the Baptist was the prophet God sent to prepare the way for Jesus. Born to Zacharias and Elisabeth, he preached repentance in the wilderness, baptized many in the Jordan, and pointed the crowds to Christ as the Lamb of God. He was later imprisoned and martyred for his faithfulness.
John the Baptist stands at the hinge of the Bible, the last of the great prophets and the herald of the Messiah. He lived simply in the desert, wearing rough clothing of camel's hair and eating locusts and wild honey, and his preaching drew crowds from Jerusalem and all Judaea. Yet everything about John pointed beyond himself. He came not to gather followers to his own name but to make ready a people for the Lord. Below are five passages, quoted exactly from the King James Version, that show his message, his mission, and the greatness Jesus Himself attributed to him.
What did John the Baptist preach?
John's message was short, urgent, and searching. He called people to turn from sin because God's promised kingdom was drawing near in the person of the coming King.
"And saying, Repent ye: for the kingdom of heaven is at hand." — Matthew 3:2 (KJV)
To repent is to change direction — to turn from sin and toward God. John did not soften the summons; he made it plain. The kingdom was "at hand," near enough to touch, and the only fitting response was a changed heart. His preaching prepared the soil so that the seed of the gospel could take root.
How did John describe himself?
When priests and Levites came asking who he was, John refused every grand title. He described himself simply as a voice — and he borrowed the words of the prophet Isaiah to do it.
"He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias." — John 1:23 (KJV)
A voice exists to carry a message, not to be admired for itself. John saw his whole life that way. His humility is striking — he would later say of Jesus, "He must increase, but I must decrease" (John 3:30, KJV). Here was a man entirely content to be the finger that points, so long as it pointed to the right One.
Why did John baptize, and whom did he announce?
John baptized those who repented as a sign of their turning to God. But he was always careful to say that his baptism was only a beginning, and that One far greater was coming after him.
"I indeed baptize you with water unto repentance: but he that cometh after me is mightier than I, whose shoes I am not worthy to bear: he shall baptize you with the Holy Ghost, and with fire:" — Matthew 3:11 (KJV)
John drew a clear line between himself and the Messiah. His water pointed to something deeper that only Christ could give. And when Jesus came to him, John named Him for all to hear:
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world." — John 1:29 (KJV)
In one sentence John summed up the whole gospel. Jesus is the Lamb — the sacrifice God Himself provides — who takes away not merely the sins of a nation but the sin of the world. This is the truth John lived and died to announce.
How did Jesus honour John?
John's faithfulness cost him his freedom and finally his life; he was imprisoned by Herod and put to death. Yet Jesus spoke of him with the highest honour.
"Verily I say unto you, Among them that are born of women there hath not risen a greater than John the Baptist: notwithstanding he that is least in the kingdom of heaven is greater than he." — Matthew 11:11 (KJV)
Jesus called no one born of woman greater than John — a stunning tribute to a man who owned nothing and sought no fame. And yet Jesus added that the least in the kingdom is greater still, reminding us that the greatest privilege is not John's role but the gift of belonging to Christ's kingdom, which John gave his life to prepare.
Frequently asked questions
What was John the Baptist's mission?
John was the forerunner of the Messiah, sent to prepare people's hearts for Jesus. He preached, Repent ye: for the kingdom of heaven is at hand (Matthew 3:2, KJV), and described himself as the voice of one crying in the wilderness, Make straight the way of the Lord (John 1:23, KJV). His whole ministry pointed away from himself and toward Christ.
Why did John call Jesus the Lamb of God?
When John saw Jesus he declared, Behold the Lamb of God, which taketh away the sin of the world (John 1:29, KJV). The title draws on the Old Testament sacrificial system, where a lamb was offered for sin. John was announcing that Jesus is the true sacrifice God provided, the one who would take away sin by His own death.
"He was a burning and a shining light: and ye were willing for a season to rejoice in his light." — John 5:35 (KJV)
