Very much so. In the Gospel of Mark the coming of John the Baptist is considered to be “the beginning of the gospel of Jesus Christ…” (Mark 1: 1). The difference John would make to history was so great that it was prophesied centuries before his birth that he would prepare the way for the Messiah.  

John the Baptist was the turning point in prophetic history. Until this time the old Covenant prophets had interpreted, confirmed, and applied the law in a moral dimension. John, by the commandment of God, introduced a new message: “The kingdom is ready, are you?” 

John fulfilled Isaiah’s promise of a voice to prepare the Messiah’s way. 

After 400 years of silence, God was again speaking prophetically in Israel. But the message was entirely new. It heralded a coming king and a new law. Preparation must be made not only in individual hearts but in society if they are to receive their Messiah.  

The voice of him that crieth in the wilderness. Prepare ye the way of the LORD, make straight in the desert a highway for our God. Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain (Isaiah 40: 3, 4).  

 John fulfilled Malachi’s promise of a herald or forerunner before the Messiah. 

The people were so unaccustomed to hearing God speak that they needed a messenger before the messenger. Jesus himself was the messenger as well as the mediator of the New Covenant which ushered in the kingdom. But before people could be alerted to hear Him, they needed to be awakened through the prophetic preaching and baptism of John, the forerunner or herald.  

Behold, I will send my messenger, and he shall prepare the way before me: and the LORD, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the lord of hosts (Malachi 3: 1).  

John came with a special ability from God to draw people to repentance. 

John came in the “spirit and power of Elijah.” In this way, he fulfilled the promise to Malachi that Elijah would come again before the Messiah came. This anointing from God gave John a special ability to stir the hearts of parents and children alike and to lead them to repentance.  

Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD: And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse (Malachi’s 4: 5, 6).  

John brought the old Covenant dispensation to an end. 

The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it (Luke 16: 16).
