Jesus himself made a very powerful statement when he said, “I am the way, the truth and the life, no man comes to the Father but by me.”
These words live in infamy and he is making a proclamation that no other man in history has ever said.
I am – In the Greek language, “I am” is a very intense way of referring to oneself. It would be comparable to saying, “I myself, and only I, am.” Several other times in the Gospels we find Jesus using these words. In Matthew 22:32 Jesus quotes Exodus 3:6, where God uses the same intensive form to say, “I am the God of Abraham, and the God of Isaac, and the God of Jacob.” In John 8:58, Jesus said, “Truly, truly I say unto you, before Abraham was, I am.” The Jews clearly understood Jesus to be calling Himself God because they took up stones to stone Him for committing blasphemy in equating Himself with God. In Matthew 28:20, as Jesus gave the Great Commission, He gave it emphasis by saying, “I am with you always, to the end of the age.” When the soldiers came seeking Jesus in the garden the night before His crucifixion, He told them, “I am he,” and His words were so powerful that the soldiers fell to the ground (John 18:4–6). These words reflect the very name of God in Hebrew, Yahweh, which means “to be” or “the self-existing one.” It is the name of power and authority, and Jesus claimed it as His own.
The way – Jesus used the definite article to distinguish Himself as “the only way.” A way is a path or route, and the disciples had expressed their confusion about where He was going and how they could follow. As He had told them from the beginning, Jesus was again telling them (and us) “follow me.” There is no other path to heaven, no other way to the Father. Peter reiterated this same truth years later to the rulers in Jerusalem, saying about Jesus, “Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved” (Acts 4:12). The exclusive nature of the only path to salvation is expressed in the words “I am the way.”
The truth – Again Jesus used the definite article to emphasize Himself as “the only truth.” Psalm 119:142 says, “Your law is the truth.” In the Sermon on the Mount, Jesus reminded His listeners of several points of the Law, then said, “But I say unto you . . .” (Matthew 5:22, 28, 32, 34, 39, 44), thereby equating Himself with the Law of God as the authoritative standard of righteousness. In fact, Jesus said that He came to fulfill the Law and the prophets (Matthew 5:17). Jesus, as the incarnate Word of God (John 1:1) is the source of all truth.
The life – Jesus had just been telling His disciples about His impending death, and now He was claiming to be the source of all life. In John 10:17–18, Jesus declared that He was going to lay down His life for His sheep, and then take it back again. He spoke of His authority over life and death as being granted to Him by the Father. In John 14:19, He gave the promise that “because I live, you also will live.” The deliverance He was about to provide was not a political or social deliverance (which most of the Jews were seeking), but a true deliverance from a life of bondage to sin and death to a life of freedom in eternity.
