Commentaries:
During the Passover service, we always read John 14 in its entirety. It is chock-full of insight and instruction that we, as Christ's disciples, need to live fully as Christians and to prepare for eternal life in the Kingdom of God.
Jesus sets the goal before us, eternal life in God's house. He says that He will soon be going to that same goal, where He will be in a better position to prepare us to reach it. Then He says, "You know the way there," which has Thomas scratching his head. "Lord, we do not know where You are going, and how can we know the way?" (verse 5). In other words, if we do not have a clear idea of the goal, how can we find our way there? It is impossible. A person must have a destination in mind before he can map out the route.
In verse 6, Jesus provides the answer: "I am the way, the truth, and the life. No one comes to the Father except through Me." Jesus' emphasis is on "the way" since that is the force of Thomas' question. Some commentators have even gone so far as to say that the real sense of His statement is, "I am the true and living way"—that is, the words "life" and "truth" modify "way."
He implies that the Father will only accept as His children those who imitate the character and process of salvation that Christ pioneered. He is called the Captain or Author of our salvation (Hebrews 2:10). Jesus has blazed the trail before us, showing us the way to go—and the way to go is to follow in His footsteps, to imitate Him (I John 2:6). There is only one road that leads to the Kingdom of God, the road that Christ Himself trod.

Christ, the Way
They did not know the way quite as well as Christ may have liked that they did. This is why Thomas asked in verse 5, "How can we know the way?"
