15 Perceiving then that they were about to come and take him by force to make him king, Jesus withdrew again to the mountain by himself.
16 When evening came, his disciples went down to the sea, 17 got into a boat, and started across the sea to Capernaum. It was now dark, and Jesus had not yet come to them. 18 The sea became rough because a strong wind was blowing. 19 When they had rowed about three or four miles,[1] they saw Jesus walking on the sea and coming near the boat, and they were frightened. 20 But he said to them, "It is I; do not be afraid." 21 Then they were glad to take him into the boat, and immediately the boat was at the land to which they were going.
22 On the next day the crowd that remained on the other side of the sea saw that there had been only one boat there, and that Jesus had not entered the boat with his disciples, but that his disciples had gone away alone. 23 Other boats from Tiberias came near the place where they had eaten the bread after the Lord had given thanks. 24 So when the crowd saw that Jesus was not there, nor his disciples, they themselves got into the boats and went to Capernaum, seeking Jesus.

Commentary on John 6:15-21
(Read John 6:15-21)
Here were Christ's disciples in the way of duty, and Christ was praying for them; yet they were in distress. There may be perils and afflictions of this present time, where there is an interest in Christ. Clouds and darkness often surround the children of the light and of the day. They see Jesus walking on the sea. Even the approaches of comfort and deliverance often are so mistaken, as to become the occasions of fear. Nothing is more powerful to convince sinners than that word, "I am Jesus whom thou persecutest;" nothing more powerful to comfort saints than this, "I am Jesus whom thou lovest." If we have received Christ Jesus the Lord, though the night be dark, and the wind high, yet we may comfort ourselves, we shall be at the shore before long.
Commentary on John 6:22-27
(Read John 6:22-27)
Instead of answering the inquiry how he came there, Jesus blamed their asking. The utmost earnestness should be employed in seeking salvation, in the use of appointed means; yet it is to be sought only as the gift of the Son of man. Him the Father has sealed, proved to be God. He declared the Son of man to be the Son of God with power.
