Mark 6:48-52

Then He saw them straining at rowing, for the wind was against them. Now about the fourth watch of the night He came to them, walking on the sea, and would have passed them by. And when they saw Him walking on the sea, they supposed it was a ghost, and cried out; for they all saw Him and were troubled. But immediately He talked with them and said to them, “Be of good cheer! It is I; do not be afraid.” Then He went up into the boat to them, and the wind ceased. And they were greatly amazed in themselves beyond measure, and marveled. For they had not understood about the loaves, because their heart was hardened.
