16 When evening came, his disciples went down to the sea, 17 got into a boat, and started across the sea to Caper'na-um. It was now dark, and Jesus had not yet come to them. 18 The sea rose because a strong wind was blowing. 19 When they had rowed about three or four miles, they saw Jesus walking on the sea and drawing near to the boat. 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.

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.
