The Preparing Message of John
7He said therefore to the multitudes who went out to be baptized by him, “You offspring of vipers, who warned you to flee from the wrath to come? Luke 3:7
Even the truly wicked will sometimes make a show of repentance in the hopes of missing the righteous judgment of God. They know that their works are evil and that the wages of sin is death (Romans 6:23) and know that Yahweh has promised to spare those who return to Him.
However, these same wicked people do not fully realize that God knows the hearts of all men. He also can see the actions of humankind. When a person says they have repented from their sin, what follows should be proof. Yet many expected that saying with the mouth was all that was needed.
John's Preparation
John the Baptizer, the prophet of Yahweh and preparer of the way of the Lord Jesus, didn't allow them to think this behavior would be accepted by God.
8Therefore produce fruits worthy of repentance, and don’t begin to say among yourselves, ‘We have Abraham for our father;’ for I tell you that God is able to raise up children to Abraham from these stones! Luke 3:8
It was not enough to count upon one's physical heritage to claim the blessings of the Covenant. These Jews could not depend on Abraham as their ancestor to bring them a right standing with Yahweh. God could raise up new children out of inanimate stones if He chose. Yet He desired His people to be willing participants in the Covenant. He desired them to do what was right to prove they truly loved Him. And He was not giving them much longer to decide what they would do.
9Even now the ax also lies at the root of the trees. Every tree therefore that doesn’t produce good fruit is cut down, and thrown into the fire.” Luke 3:9
It is often the case with some types of people that this kind of information is what is necessary to awaken them to reality. They realized they could not rely upon their ancestry to make themselves pure before their God. They understood that the time was coming when Yahweh would judge the whole world in righteousness, according to its works. And fortunately, this people did not reject outright what John had been saying; they wanted to know where to go from where they had been.
10The multitudes asked him, “What then must we do?” Luke 3:10
John's answer was the heart of Jesus' Gospel that was to come.
11He answered them, “He who has two coats, let him give to him who has none. He who has food, let him do likewise.” Luke 3:11
This act began with the act of loving oneself; namely that a person had provided for their own well being by having clothing. It continued with the act of loving the person's neighbor, by being willing to and actually working to give from one's excess to meet another person's need. Both with clothing and food, John's advice was to have what you needed first, and from the extra to give to others. He did not say if you have one coat, give it to the one who has none. For then the first person would be the one with none and the one to whom he gave would be obligated to give it back! Rather, those who had two, one for their own self and thus one for another, were to give that extra. And the one with food, "let him do likewise."
Here is the beginning of repentance from dead works; it is bringing forth fruit worthy of repentance. It is not working for the sake of working, but out of a true desire to love one's self and others. It is seeing needs and meeting them as one is able. It is living from love.
The Lord's Gospel
Christ's way was prepared by the ministry of John, as prophesied by Isaiah.
1In those days, John the Baptizer came, preaching in the wilderness of Judea, saying, 2“Repent, for the Kingdom of Heaven is at hand!” 3For this is he who was spoken of by Isaiah the prophet, saying, “The voice of one crying in the wilderness, make ready the way of the Lord. Make his paths straight.” Matthew 3:1-3
Notice that Jesus' Gospel was an affirmation of what John had already taught the people.
17From that time, Jesus began to preach, and to say, “Repent! For the Kingdom of Heaven is at hand.” Matthew 4:17
15and saying, “The time is fulfilled, and God’s Kingdom is at hand! Repent, and believe in the Good News.” Mark 1:15
The second part of the Word of Christ was to "believe in the Gospel." This is the second part of Word of Christ, according to the writer of Hebrews (Hebrews 6:1): that of faith, of trust. The Lord wished His listeners to first repent, and then to trust in the Gospel.
