Time of His Ministry
Only Luke tells us when John the Baptist started his ministry. He does not give us a calendar date but tells us that John began his ministry in the desert during the reigns of several individuals and at the time of two high priests.
Now in the fifteenth year of the reign of Tiberius Caesar, when Pontius Pilate was governor of Judea, and Herod was tetrarch of Galilee, and his brother Philip was tetrarch of the region of Ituraea and Trachonitis, and Lysanias was tetrarch of Abilene, in the high priesthood of Annas and Caiaphas, the word of God came to John, the son of Zacharias, in the wilderness. Luke 3:1-2 (NASB)
If we count fifteen years after the start of Tiberius Caesar’s reign, we discover that John’s ministry began in A.D. 29, since Tiberius Caesar ruled from A.D. 14 to A.D. 37. The reigns of Pontius Pilate, Herod Antipas, and Herod Philip all overlap A.D. 29. This helps us determine precisely the time when John started his ministry. Jesus’ ministry started some time later – maybe as late as A.D. 30.
The major question is how could both Annas and Caiaphas be high priests of Israel at the same time? The answer is found in the fact that Rome did not want Annas to be the chief priest and consequently replaced him with Caiaphas (A.D. 18 – 37). While Caiaphas was the official high priest, the Jews continued to consider Annas to be the real high priest. That is, Israel had one official high priest and one popular high priest.
So Luke has given us precise information. But why? Why tell us when John the Baptist started his ministry? Why provide all of this detail? The answer is simple. Luke does not consider John the Baptist to be a fictional character. Christians often talk about “the story of Adam and Eve,” “the story of Moses,” or the “story of Samson.” Some consider these to be myths and stories for children. But the truth is these are not just stories. They represent real people, people who really existed. They did real things, and Luke believes that John the Baptist was a real person. Otherwise, why provide us with such details about the start of John’s ministry? It is obvious that Luke considers John the Baptist to be a real person who did real things! We will see in the next few verses that Luke will provide us with more details. He is not finished.
Location of His Ministry
The gospels of Matthew, Mark, and Luke each also provide us with different clues as to the region where John did his ministry. Matthew says that he preached in the wilderness of Judea.
Now in those days John the Baptist came, preaching in the wilderness of Judea . . . Matthew 3:1 (NASB)
And all the country of Judea was going out to him, and all the people of Jerusalem . . . Mark 1:5 (NASB)
And he came into all the district around the Jordan . . . Luke 3:3 (NASB)
Mark adds that people from Jerusalem were visiting him, and Luke says that John was ministering near the Jordan River which flows from the Sea of Galilee down to the Dead Sea. This means that John was probably ministering near the northwest corner of the Dead Sea and near the Jordan River. The gospel writers believed that John really existed, and did real things. He was a real guy!
The gospels are based in historical fact and not fiction. God did this for a reason. Christianity is not based on “stories” or fanciful myth. Christianity is based on fact and from fact follows faith and then feeling. Because there is fact, we believe, and then the feeling follows. Too often Christians seek feelings and ignore facts. The gospel writers started with facts. There are no “feeling” statements here. Why? Because we must start with facts first. Then we believe, and the feeling comes last. Christianity is based on truth!
All three gospels tell us that John the Baptist was an important man in history. He arrived in time and place for a purpose. He was the fulfillment of ancient prophecies.
As it is written in Isaiah the prophet: “BEHOLD, I SEND MY MESSENGER AHEAD OF YOU, WHO WILL PREPARE YOUR WAY;” Mark 1:2 (NASB)
. . . THE VOICE OF ONE CRYING IN THE WILDERNESS, “MAKE READY THE WAY OF THE LORD, MAKE HIS PATHS STRAIGHT. ‘EVERY RAVINE WILL BE FILLED, AND EVERY MOUNTAIN AND HILL WILL BE BROUGHT LOW; THE CROOKED WILL BECOME STRAIGHT, AND THE ROUGH ROADS SMOOTH; AND ALL FLESH WILL SEE THE SALVATION OF GOD.” Luke 3:4-6 (NASB)
Mark adds something that none of the other gospels include and Luke includes all of the other fulfillments quoted by Matthew and Mark. Mark quotes the prophecy from Malachi 3:1, and Luke quotes Isaiah 40:3-4. Both prophecies predict the coming of one who will prepare the people for the coming of the Messiah. Malachi 3:1 says that Messiah will “suddenly come to His temple,” and Jesus did just that at the start of His own ministry. We will see shortly that John was preparing the Jewish people for Jesus – their Messiah.
But what is Isaiah 40:3-4 all about? At first the prophecy does not seem to have any special meaning. It appears to just be figurative language. The reason for this impression is that we are missing an important cultural fact. The emphasis of Isaiah 40:3-4 is not just the “voice of one crying in the wilderness.” The emphasis includes what follows. Ancient history tells us that when a king, governor, or someone of importance came to visit, road crews were sent out to prepare the roads for his coming. The roads were literally straightened, potholes were filled, rocks and debris were removed, and the roads were smoothed. The message of Isaiah 40 is that the forerunner would straighten the spiritual path. So John came preparing “the road” for Jesus. He was preparing the spiritual road. John was calling people to straighten out their spiritual lives. His message was a call to repentance – to stop sinning.
Repent, for the kingdom of heaven is at hand. Matthew 3:2 (NASB)
John the Baptist appeared in the wilderness preaching a baptism of repentance for the forgiveness of sins . . . and they were being baptized by him in the Jordan River, confessing their sins. Mark 1:4-5 (NASB)
. . . preaching a baptism of repentance for the forgiveness of sins. Luke 3:3 (NASB)
This illustration of preparing the road is a symbol of repentance. That is what John the Baptist called the people to do – repent!
Call to Repentance
John used baptism as an external illustration of inward repentance. In Jesus’ day baptism was for those Gentiles who desired to become converts to Judaism. The Qumran community used it in a ritual way, but John the Baptist used it as a symbol of a repentant heart. John’s baptism was a sign of an inward change – a repentant heart.
John was calling people to act differently: to flee from sin – to change their hearts and lives. So when some unrepentant Pharisees and Sadducees came to him, he responded with some harsh words,
But when he saw many of the Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers, who warned you to flee from the wrath to come?” Matthew 3:7 (NASB)
Therefore bear fruits in keeping with repentance, and do not begin to say to yourselves, “We have Abraham for our father,” for I say to you that from these stones God is able to raise up children to Abraham. Indeed the axe is already laid at the root of the trees; so every tree that does not bear good fruit is cut down and thrown into the fire. Luke 3:8-9 (NASB)
Their lives did not demonstrate repentant hearts; there was no fruit. These religious leaders thought that they would be able to enter heaven because they were descendants of Abraham. The “good old boy” network was all they needed. They assumed God worked that way. So John reminded them that God could make anyone His “children” – even stones; and unless they truly repented of their sins (changed their lives) God would destroy them too! That is the meaning of John’s figurative language about the tree being cut down and burned.
The crowds understood John’s message and so they asked, “What shall we do?”
And the crowds were questioning him, saying, “Then what shall we do?” And he would answer and say to them, “The man who has two tunics is to share with him who has none; and he who has food is to do likewise.” Luke 3:10-11 (NASB)
John told them to share food and clothes with others. A truly repentant, godly heart will respond to the need of others. The unrepentant will not.
To the tax collectors, John encouraged them to collect only those taxes which were necessary.
And some tax collectors also came to be baptized, and they said to him, “Teacher, what shall we do?” And he said to them, “Collect no more than what you have been ordered to.” Luke 3:12-13 (NASB)
In Jesus’ day the tax collectors would contract with Rome to collect a certain amount of taxes. They would outbid one another for the job. If they won, then they had to fulfill their commitment to Rome. So the tax collectors would collect more than what was required to pay-off Rome and then keep the rest. So John was simply telling them to not take advantage of their positions. Those who are in positions of authority can take advantage of others. John’s message is simple – a repentant heart will not do that.
Some soldiers also came and asked John what they should do. So he encouraged them not to take advantage of their positions either.
Some soldiers were questioning him, saying, “And what about us, what shall we do?” And he said to them, “Do not take money from anyone by force, or accuse anyone falsely, and be content with your wages.” Luke 3:14 (NASB)
A heart that has been straightened out, whose potholes have been filled, and from whom the debris of sin has been removed will love others and not abuse people. These are the fruits of the good tree that John was preaching about.
How did the people respond?
Now while the people were in a state of expectation and all were wondering in their hearts about John, as to whether he was the Christ . . . Luke 3:15 (NASB)
The people wanted to know if John was the Christ or the Messiah. The Greek word for “was” is in the optative mood. This mood is rare in the New Testament, and it means that people were constantly wishing that John was the Christ. John was popular! Just think. How would you feel inside if a crowd of people were hoping and wishing that you were someone important? How would you respond to their questions? After being repeatedly asked, might you want to say, “Yes!” John was a very humble man. He came dressed in garments of camel’s hair with a leather belt around his waist, and his food was locusts and wild honey (Matt. 3:4). He did not appear as a wealthy man. He had given up the comforts of the priesthood and the opportunity to serve in the temple in Jerusalem. He did not follow in the footsteps of his father Zacharias. His home was the desert along with all of the wild animals. He was not part of the “name it and claim it” crowd. He was a humble man and so he said this.
John answered and said to them all, “As for me, I baptize you with water; but One is coming who is mightier than I, and I am not fit to untie the thong of His sandals; He will baptize you with the Holy Spirit and fire. His winnowing fork is in His hand to thoroughly clear His threshing floor, and to gather the wheat into His barn; but He will burn up the chaff with unquenchable fire.” So with many other exhortations he preached the gospel to the people. Luke 3:16-18 (NASB)
So John compares himself to the Messiah’s ministry and Messiah’s character. On both points, he says that he is inferior. He was not the Messiah.
First, John said that he only baptized with water, but the Messiah would baptize with the Holy Spirit and fire. Jesus has already accomplished the first part. He has sent the Holy Spirit when He left this world and ascended up into heaven. Today, the Holy Spirit “baptizes” believers into the spiritual church called the “body of Christ” (1 Corinthians 12:13). He will also bring fire and destroy the world when the end of time has arrived. Some day God will also put unbelievers or those who ultimately reject Him into the Lake of Fire. So John was correct.
Second, John says that he is not worthy to untie Jesus’ shoes. Here in the twentieth century we miss something. But at the time of Jesus, only slaves were expected to untie their master’s shoes. Such an act was considered beneath the dignity of others. So when John says that he is not worthy to unite the Messiah’s shoes, he is saying that he is beneath a slave. Now that is humble!
Are you a sandal untier? John the Baptist was! He was the forerunner for the Messiah yet he acted like a poor man. He was not a proud man. He had a ministry to perform – a ministry that God had given him. He was not puffed up like a balloon because he was God’s man. He did not yield to the wishes of the people who wanted him to be something more than he was. John the Baptist was simply God’s man, doing God’s ministry. He knew that the response of the people was only because God was working through him. Now that is humble.
How about you? Are you a leader in the church? Are you a pastor, an elder, a teacher, a leader of men or women, or maybe a missionary? Recently, some individuals have talked about what they have done for the Lord, and added that it is okay to take credit. Not John! Psalm 127:1-2 reminds us that it is God who is at work. Without Him we can do nothing (John 15:5). John is an example of greatness in God’s kingdom. He was the forerunner with a humble heart!
St. Augustine was once asked what was the most important characteristic of a believer in the Christian religion. He replied, “Humility.” “And what was the second?” – “Humility.” “And what was the third?” – “Humility!” Therefore, let us ask ourselves, “Am I a sandal untier?”
