Shall thy wonders be known in the dark? and thy righteousness in the land of forgetfulness? But unto thee have I cried, O LORD; and in the morning shall my prayer prevent thee. LORD, why castest thou off my soul? why hidest thou thy face from me? Psalm 88:12-14
 
And entered into a ship, and went over the sea toward Capernaum. And it was now dark, and Jesus was not come to them. And the sea arose by reason of a great wind that blew. So when they had rowed about five and twenty or thirty furlongs, they see Jesus walking on the sea, and drawing nigh unto the ship: and they were afraid. But he saith unto them, It is I; be not afraid. Then they willingly received him into the ship: and immediately the ship was at the land whither they went. 
John 6:17-21
