Matthew 14:30

βλέπων τὸν ἄνεμον, seeing the wind, that is, the effects of it. It is one thing to see a storm from the deck of a stout ship, another to see it in midst of the waves. καταποντίζεσθαι : he walked at first, now he begins to sink; so at the final crisis, so at Antioch (Galatians 2:11), so probably all through. A strange mixture of strength and weakness, bravery and cowardice; a man of generous impulses rather than of constant firm will. “Peter walked on the water but feared the wind : such is human nature, often achieving great things, and at fault in little things.” (πολλάκις τὰ μεγάλα κατορθοῦσα, ἐν τοῖς ἐλάττοσι ἐλέγχεται, Chrys., H. 1.)
