Luke is the only one of the four evangelists who does not narrate the story of Jesus walking on the water. In Matthew (14:22-32), and Mark (6:45-51), like in John, the miracle is narrated immediately after the feeding of the five thousand. John’s account of the miracle is the shortest of the three.
The story begins by portraying the disciples in a boat moving towards Capernaum. The statement that “it was now dark” indicates, on the surface level, the time of the day, but on the deeper level, the absence of Jesus. It is always “dark” for John when Jesus is absent. The rough sea and the strong wind make rowing difficult. Suddenly, the disciples see Jesus walking on the water, coming towards them. In the Old Testament, only God has the power to walk on the waters (Job 9:8; Isa 43:2), and so, this act on the part of Jesus, already reveals him as divine. John does not give us the reason why the disciples were terrified. Matthew (14:26) and Mark (6:49) explain the fear of the disciples by saying that they thought they saw a ghost.
As Jesus comes close to the boat, he identifies himself to the disciples with the divine name, “I Am”. This is the name that God gave to Moses when Moses asked God for the name that he must give to the Israelites when asked (Exod 3:14). In addition to identifying himself with the divine name, Jesus says to the disciples, “Do not be afraid”. These are words of comfort and consolation and, here also, function to allay the fears of the disciples who are in awe after witnessing a theophany. Even as the disciples want to take Jesus into the boat, they realize that they have reached their destination. The presence of Jesus assures them a safe passage through all the storms.
Thus, the point of the miracle is not so much to stress the miraculous powers of Jesus, but to reveal Jesus as God. The glory of God is revealed in Jesus and here, God is portrayed as a God who is for the disciples and with them in all their struggles and tribulations. He is a God who comes to the disciples’ aid when they need him and allays all their fears. He is a God who will provide a safe passage for them even in the midst of all the storms they encounter in life.
