In this section Luke give three examples of John preaching (Luke 3:7-9, 10-14, 15-17). His first sermon is eschatological (Luke 3:3-9) and states that the Kingdom of God has come (see below). Therefore John stresses repentance. In his second discourse (Luke 3:10-14), John gives various ethical instructions describing the fruits that naturally accompany true repentance. Royal subjects (cf. 1 Pet. 2:9) of God's Kingdom act differently. We also learn therefore that baptism (a work, Eph. 2:10) does not save. In his last discourse (Luke 3:15-17), John announces the coming Messiah. He follows this with a concluding summary of his ministry (Luke 3:18) and a historical summary of what will then transpire (Luke 3:19-20) .
John saw the crowds coming out to him to be baptized. His words to them were prophetic. He says:
You brood of vipers! Who warned you to flee from the coming wrath? 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.
John under the Spirit says repent because the Kingdom of God ("coming wrath") has come (see below). The Kingdom of God is inaugurated in the life, death, and resurrection of Christ, it continues in the Church today, and will come into its fullness in the consummation of all things at the Second Coming.
John calls his hearers snakes. God's enemies are often called snakes (Isa. 14:29; 59:5; Jer. 46:22). So, John is warning the people that God's Kingdom is here now, but their hearts are not right with God. The reference to "coming wrath" alludes to the Day of the Lord (Isa. 13:9; 30:23; Zeph. 2:2-3; Mal 3:2; 4:1, 5). This a strong warning is directed at those who claimed Abraham as father. Merely being a Jew would not deliver a person from the coming wrath. Mere association with the Old Testament Church, or any other Church, would not do. The need of the hour, rather every hour, is repentance.
Repentance means a change of mind, to alter one's direction, or modify one's perspective on something, or change sides or points of view. As Paul says to go "from" previously serving idols "to" serving the living God (1 Thess. 1:9-10; cf. Luke 6:43-45; 13:6-9). True repentance (2 Cor. 7:10) is the proper response to the Gospel's message (Luke 24:47).
True repentance may be identified. The gift of repentance given by the Spirit (2 Tim. 2:24-26) is accompanied with true change; with true fruit. "Fruit" in the Greek is plural, so John is saying fruitfulness, multiple types of fruit. John states a few of the changes those who truly repent will see. The repentant trees will bare fruit.
In Luke 3:11 he mentions the tunic. The tunic was an undergarment. Normally only one was worn. John suggested that the man who had two should give the spare to someone without one, and the prophet applied the same principle to food. In Luke 3:12 the tax collector is mentioned. That is the agents of Roman taxation (men who bid for the taxing rights of a city). They would pay the Romans what they bid and collect more for themselves. There was a strong temptation for them to enrich themselves by collecting much more than the amount due. Then in Luke 3:14 we see the Kingdom command of don't extort. John admonished all to be honest. All four Gospels include an account of the ministry of John the Baptist as he called people to repentance in preparation for the coming of Jesus. Only Luke's Gospel tells us of John's answers to questioners who were uncertain about what all this meant to them. See WCF 23.3; HC 110.
So, John points them to their homes, jobs, and personal relationships. True repentance is a matter of the heart and results in change in everyday behavior. In other words, "Love the Lord your God with all your heart, all your soul, all your strength, and all your mind. Also, Love your neighbor the same as you love yourself" (Luke 10:27). Be Good Samaritans (Luke 10:25-37). This is the fruit that accompanies true God-given repentance.
The ax is already at the root of the trees (Luke 3:9). The poised ax makes it clear that any unfruitful tree will be removed and burned. Repent for the Kingdom and its judgment is here! This phrase points to certain and speedy judgment. fire. A symbol of judgment (cf. Deut. 32:22; Isa. 26:11). Like his contemporaries, John expected the Messiah simultaneously to bring salvation for God's people and judgment against God's enemies. When Jesus did not do this, serious questions were raised in John's mind (Matt. 11:3). Jesus explained that the Kingdom of God was coming in a way that had not been previously foreseen.
With such powerful teaching, the people wondered if John might be the Christ (Luke 3:15). However, John answered them saying:
"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. His winnowing fork is in his hand to clear his threshing floor and to gather the wheat into his barn, but he will burn up the chaff with unquenchable fire."
Not only is the Kingdom of God here, so is its King, so is its Messiah, Immanuel, God with us (Matt. 1:23; cf. Isa. 9:6; Luke 1:31-33). Messianic speculations were in the air, but John stated clearly that he himself was not the Messiah. One greater than John was coming, whose sandals he was not worthy to untie (Luke 3:15-16). In the rabbinic schools, a student did not pay his teacher. He was required to perform services - but not the loosing of the sandal, which was considered too menial. John took a lowly place.
The Christ would baptize with the Holy Spirit and with fire (Luke 3:16-17). The Holy Spirit represented God's blessing as well as fire, which points to judgment (Luke 3:9). The winnowing fork also implied judgment. It was used to throw the crop into the air after it had been trodden by oxen. This separated the chaff (which was then burned) from the grain.
John taught the people many things about the Good News of the Kingdom (Luke 3:18). Then Luke tells us of John's imprisonment and death (Luke 3:19). Herod Antipas divorced his wife and married his niece Herodias, who had been married to his own brother (see note on Mark 6:18). John denounced this immoral act, so Herod confined him in prison in the fortress of Machaerus, east of the Dead Sea. The message of the Kingdom is not received the same by all.
vipers. A non-specific word that includes a variety of poisonous snakes. The implication of John's statement is that some in ethnic Israel were living faithlessly as the Serpent's seed (see Gen. 3:15; Isa. 59:5; John 8:44). warned. Like snakes fleeing a burning pile of brush, these were coming for baptism to escape wrath (see Isa. 13:9; 30:27). But they were not sincere. They lacked faith and the fruits of true repentance. children of Abraham. Many of those who went to John had pride in their Jewish heritage and trusted in it to make them right before God (see John 8:39-40, 53). John's harsh message was meant to awaken people to their sin and need to trust God.
