Isaiah 40:3-5

40:3 A voice cries out,

“In the wilderness clear a way for the Lord;

construct in the desert a road for our God.

40:4 Every valley must be elevated,

and every mountain and hill leveled.

The rough terrain will become a level plain,

the rugged landscape a wide valley.

40:5 The splendor of the Lord will be revealed,

and all people will see it at the same time.

For the Lord has decreed it.”

Matthew 3:1-3

The Ministry of John the Baptist

3:1 In those days John the Baptist came into the wilderness of Judea proclaiming, 3:2 “Repent, for the kingdom of heaven is near.” 3:3 For he is the one about whom Isaiah the prophet had spoken:

“The voice of one shouting in the wilderness,

‘Prepare the way for the Lord, make his paths straight.’”

Matthew 17:10-13

17:10 The disciples asked him, “Why then do the experts in the law say that Elijah must come first?” 17:11 He answered, “Elijah does indeed come first and will restore all things. 17:12 And I tell you that Elijah has already come. Yet they did not recognize him, but did to him whatever they wanted. In the same way, the Son of Man will suffer at their hands.” 17:13 Then the disciples understood that he was speaking to them about John the Baptist.

Luke 1:16-17

1:16 He will turn many of the people of Israel to the Lord their God. 1:17 And he will go as forerunner before the Lord in the spirit and power of Elijah, to turn the hearts of the fathers back to their children and the disobedient to the wisdom of the just, to make ready for the Lord a people prepared for him.”

Luke 3:3-6

3:3 He went into all the region around the Jordan River, preaching a baptism of repentance for the forgiveness of sins.

3:4 As it is written in the book of the words of Isaiah the prophet,

“The voice of one shouting in the wilderness:

‘Prepare the way for the Lord,

make his paths straight.

3:5 Every valley will be filled,

and every mountain and hill will be brought low,

and the crooked will be made straight,

and the rough ways will be made smooth,

3:6 and all humanity will see the salvation of God.’”

John 1:15-23

1:15 John testified about him and shouted out, “This one was the one about whom I said, ‘He who comes after me is greater than I am, because he existed before me.’” 1:16 For we have all received from his fullness one gracious gift after another. 1:17 For the law was given through Moses, but grace and truth came about through Jesus Christ. 1:18 No one has ever seen God. The only one, himself God, who is in closest fellowship with the Father, has made God known.

The Testimony of John the Baptist

1:19 Now this was John’s testimony when the Jewish leaders sent priests and Levites from Jerusalem to ask him, “Who are you?” 1:20 He confessed – he did not deny but confessed – “I am not the Christ!” 1:21 So they asked him, “Then who are you? Are you Elijah?” He said, “I am not!” “Are you the Prophet?” He answered, “No!” 1:22 Then they said to him, “Who are you? Tell us so that we can give an answer to those who sent us. What do you say about yourself?”

1:23 John said, “I am the voice of one shouting in the wilderness, ‘Make straight the way for the Lord,’ as Isaiah the prophet said.”

John 1:33-34

1:33 And I did not recognize him, but the one who sent me to baptize with water said to me, ‘The one on whom you see the Spirit descending and remaining – this is the one who baptizes with the Holy Spirit.’ 1:34 I have both seen and testified that this man is the Chosen One of God.”

John 3:28-30

3:28 You yourselves can testify that I said, ‘I am not the Christ,’ but rather, ‘I have been sent before him.’ 3:29 The one who has the bride is the bridegroom. The friend of the bridegroom, who stands by and listens for him, rejoices greatly when he hears the bridegroom’s voice. This then is my joy, and it is complete. 3:30 He must become more important while I become less important.”

Acts 13:24-25

13:24 Before Jesus arrived, John had proclaimed a baptism for repentance to all the people of Israel. 13:25 But while John was completing his mission, he said repeatedly, ‘What do you think I am? I am not he. But look, one is coming after me. I am not worthy to untie the sandals on his feet!’

Acts 19:4

19:4 Paul said, “John baptized with a baptism of repentance, telling the people to believe in the one who was to come after him, that is, in Jesus.”
