Mark 6:48-50

48He saw them straining at the oars, because the wind was against them. Very early in the morning he came toward them walking on the sea and wanted to pass by them.

49When they saw him walking on the sea, they thought it was a ghost and cried out,

50because they all saw him and were terrified. Immediately he spoke with them and said, “Have courage! It is I. Don’t be afraid.”
