Luke · chapter 3 of 24
Updated on
Luke 3 dates the start of John's ministry to the fifteenth year of Tiberius and shows him preaching a baptism of repentance for the forgiveness of sins. John tells the people to bear fruit worthy of repentance and announces one more powerful than he. Jesus is baptized, the Spirit descends on him, and the Father calls him his beloved Son. The chapter closes with his genealogy back to Adam.
After Jesus' childhood, Luke jumps ahead about eighteen years and opens a new stage with a list of rulers, like a historian. John prepares the way promised by Isaiah, and Jesus is publicly presented by the Father. The chapter joins world history, prophecy and the beginning of Jesus' ministry.
Luke dates the scene precisely: in the fifteenth year of Tiberius Caesar, with Pontius Pilate governing Judea, Herod tetrarch of Galilee, and Annas and Caiaphas as high priests, the word of God comes to John the Baptist, son of Zechariah, in the wilderness. John goes through the region around the Jordan preaching a baptism of repentance for the forgiveness of sins, and Luke quotes Isaiah: a voice crying in the wilderness, prepare the way of the Lord.
John warns the crowds that it is not enough to be descendants of Abraham; they must bear fruit of repentance, because the ax is already at the root of the trees. People ask what they should do. John gives concrete answers: share clothing and food, tax collectors must collect no more than is due, and soldiers must not extort or complain about their pay. When the people wonder whether he is the Christ, John says one more powerful is coming, who will baptize with the Holy Spirit and fire. Herod shuts John up in prison for rebuking him over Herodias, his brother's wife.
Jesus is baptized along with the people. While he prays, heaven opens, the Holy Spirit descends on him in bodily form like a dove, and a voice from heaven calls him his beloved Son, with whom he is well pleased. Luke adds that Jesus was about thirty years old and gives his genealogy, which runs backward from Jesus through David, Abraham and Noah to Adam, the son of God.

John demands fruit worthy of repentance and warns that it is not enough to say Abraham is our father. True faith shows in conduct, and religious heritage does not replace conversion.
John says someone more powerful than he is coming, whose sandals he is not worthy to untie, and that he will baptize with the Holy Spirit and fire. John is the forerunner, not the Messiah, and points to Jesus as the one who gives the Spirit.
While Jesus prays after his baptism, heaven opens, the Spirit descends like a dove, and the Father declares that Jesus is his beloved Son. In a single moment the Father, the Son and the Spirit appear, and Jesus is confirmed for his mission.
The genealogy ends with Adam, the son of God. By going back to Adam, and not only to Abraham, Luke shows that Jesus belongs to all humanity and comes to save everyone.

Luke 3 teaches that repentance is not only a feeling but a visible change in daily life. John's answers are practical: share, be honest at work, do not abuse power. In a small group you can ask what concrete fruit each person needs to produce at home and on the job.
Jesus' baptism also reminds us that the Father delights in the Son before he performs any miracle. Our identity as God's children does not rest on what we achieve but on what Christ has already done for us. That assurance frees us to serve without anxiety.
Luke 3 ends with the genealogy that places Jesus within the history of all humanity, back to Adam. In Luke 4, this beloved Son, full of the Spirit, is led into the wilderness, where he will be tested before beginning his ministry in Galilee.
Luke gives no direct explanation. Jesus identifies with the people he came to save and is anointed with the Spirit for his mission. His baptism was not one of personal repentance but the public start of his work and the sign of the Father's approval.
It is understood in different ways. Some see one work of purifying and power, others two: the Spirit for those who believe and the fire of judgment for those who do not. The immediate context speaks of separating wheat from chaff, and Acts 2 shows the Spirit's coming at Pentecost.
Luke gives it in ascending order to Adam and differs from Matthew in several names between David and Jesus. Traditional explanations say one follows Joseph's legal line and the other Mary's, or that levirate marriages are involved; the text does not settle it, but both affirm that Jesus belongs to David's house.
