"Do not let your hearts be troubled. You have faith in God; have faith also in me. In my Father's house there are many dwelling places. If there were not, would I have told you that I am going to prepare a place for you? And if I go and prepare a place for you, I will come back again and take you to myself, so that where I am you also may be. Where (I) am going you know the way." Thomas said to him, "Master, we do not know where you are going; how can we know the way?" Jesus said to him, "I am the way and the truth and the life. No one comes to the Father except through me. (Jn 14:1-6)
A man of troubled heart does not have faith. Jesus is trying his best to make his disciples men of faith. This faith that Jesus speaks of is not on principles or dogmas. But it is on God and Jesus who is the revelation of God.
Jesus is not only the revelation but he is also the way to reach the Father. Jesus has said so much about the Father and his relationship with the Father and the whole gospel is a narration of this relationship. Yet, the disciples have not understood that Jesus has come from the father and has to go back to the Father.
What Jesus has said as “I am the way…” can trigger of many questions. People are bound to ask; are there not other ways etc? But when we read the passage in its context, what Jesus says is that He is the way to the Father in washing the feet of the others, he is the way to the Father in laying down his life for the others, he is the way to the Father in leading the sheep like a good shepherd, he is the way to the Father in feeding the people, he is the way to the Father in showing compassion and so on.
