15 When Jesus saw that they were ready to force him to be their king, he slipped away into the hills by himself.
16 That evening Jesus' disciples went down to the shore to wait for him. 17 But as darkness fell and Jesus still hadn't come back, they got into the boat and headed across the lake toward Capernaum. 18 Soon a gale swept down upon them, and the sea grew very rough. 19 They had rowed three or four miles when suddenly they saw Jesus walking on the water toward the boat. They were terrified, 20 but he called out to them, "Don't be afraid. I am here! " 21 Then they were eager to let him in the boat, and immediately they arrived at their destination!
22 The next day the crowd that had stayed on the far shore saw that the disciples had taken the only boat, and they realized Jesus had not gone with them. 23 Several boats from Tiberias landed near the place where the Lord had blessed the bread and the people had eaten. 24 So when the crowd saw that neither Jesus nor his disciples were there, they got into the boats and went across to Capernaum to look for him.

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.
