16 When evening came, his disciples went down to the lake,
17 where they got into a boat and set off across the lake for Capernaum. By now it was dark, and Jesus had not yet joined them.
18 A strong wind was blowing and the waters grew rough.
19 When they had rowed three or three and a half miles, they saw Jesus approaching the boat, walking on the water; and they were terrified.
20 But he said to them, “It is I; don’t be afraid.”
21 Then they were willing to take him into the boat, and immediately the boat reached the shore where they were heading. (John. 6:16-21)
