But immediately Jesus spoke unto them, saying,
Be of good cheer; it is I; be not afraid.
Read Chapter 14
John Chrysostom
AD 407
This word removed their fear, and caused them to take confidence. For as they knew Him not by sight, because of His marvellous kind of motion, and because of the time, He makes Himself manifest by His voice.
He did not appear immediately to them to calm the storm, but at the fourth watch, [that is, as the night was coming to its end], teaching us not to ask for a swift solution to our misfortunes but to endure them bravely. The night was divided into four parts by soldiers who stood guard in shifts, each "watch" lasting three hours. So then, sometime after the ninth hour of the night, the Lord appeared to them as God, walking on the water. But they thought it was a phantom, so extraordinary and strange was the sight. For they did not recognize Him by figure, because it was night and because of fear. He first strengthens their resolve by saying: It is I Who can do all things; take courage.
