In Isaiah 40 we find a prophetic word concerning the coming of the Lord at some future time. 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: and the glory of the LORD shall be revealed, and all flesh shall see it together: for the mouth of the LORD hath spoken it. (Isaiah 40:3-5 KJV)
In the gospels we read that John the Baptist is the fulfillment of Isaiah’s prophecy. John came as the voice of one crying in the wilderness. Mathew records, In those days came John the Baptist, preaching in the wilderness of Judea, and saying, Repent ye: for the kingdom of heaven is at hand. For this is he that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight. (Matt 3:1-3 KJV)
Mark records this concerning John, The beginning of the gospel of Jesus Christ, the Son of God; as it is written in the prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee. The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight. (Mark 1:1-3 KJV)
Luke’s gospel puts it this way concerning John the Baptist, And he came into all the country about Jordan, preaching the baptism of repentance for the remission of sins; as it is written in the book of the words of Esiais the prophet, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight. Every valley shall be filled, and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough ways shall be made smooth; and all flesh shall see the salvation of God. (Luke 3:3-6 KJV)
In John’s gospel we find John the Baptist applying this prophecy to himself, He said, I am the voice of one crying in the wilderness, Make straight the way of the Lord, as said the prophet Esaias. (John 1:23 KJV)
Now, look back to Isaiah 40:3-5 again for a moment. Who was the way going to be prepared for? The LORD. Who was a highway going to be made for? God. There was to be a forerunner who would prepare the way for the Lord God. The word translated LORD in our Bibles comes from the Hebrew word Yhovah. According to the BDB definition, this word means Jehovah = “the existing one” The proper name of the one true God. Strong’s definition is as follows. The self existant or eternal; Jehovah, Jewish national name of God: – Jehovah, the Lord. There is no doubt that this is referring to God.
When we read the above quoted verses found in the gospels, we see the word Lord. This word comes from the Greek word Kurios, and according to Thayer is the title given to God, the Messiah. Strong’s definition is as follows, (Supremacy); supreme in authority, that is (as noun) controller; by implication Mr. (as a respectful title): – God, Lord, master, Sir. As the fulfillment of Isaiah’s prophetic word, the term Lord, can only apply to God.
Jesus, the very Word of God, became flesh and came into this world as the Messiah. In one of the clearest passages of scripture concerning the deity of Christ, we read,
In the beginning was the Word, and the word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.
There was a man sent from God, whose name was John. The same came for a witness, to bear witness of the light, that all men through him might believe. He was not that light, but was sent to bear witness of that light. (John 1:1-8 KJV)
This scripture tells us that John the Baptist was sent to bear witness of Christ, the Word. Notice that this passage of scripture declares that the Word was with God, and the Word was God, declaring the divinity of the Lord Jesus Christ, existing from eternity with God the Father. We read on to see that the Word was made flesh and dwelt among us. (John 1:14) This is still speaking of Christ, His incarnation (becoming man), the one to whom John pointed to when he declared, “And I saw, and bare record that this is the Son of God.” (John 1:34) Truly, Jesus Christ is God in the flesh.
