John 6:18 And the sea arose by reason of a great wind that blew. 19 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. 20 But he saith unto them, It is I; be not afraid.
[The Desire Of Ages. pp 381>382] At the moment when they believe themselves lost, a gleam of light reveals a mysterious figure approaching them upon the water. But they know not that it is Jesus. The One who has come for their help they count as an enemy. Terror overpowers them. The hands that have grasped the oars with muscles like iron let go their hold. The boat rocks at the will of the waves; all eyes are riveted on this vision of a man walking upon the white-capped billows of the foaming sea. They think it a phantom that omens their destruction, and they cry out for fear.
Jesus advances as if He would pass them; but they recognize Him, and cry out, entreating His help. Their beloved Master turns, His voice silences their fear, “Be of good cheer: it is I; be not afraid.” As soon as they could credit the wondrous fact, Peter was almost beside himself with joy. As if he could scarcely yet believe, he cried out, “Lord, if it be Thou, bid me come unto Thee on the water. And He said, Come.” Looking unto Jesus, Peter walks securely; but as in self-satisfaction he glances back toward his companions in the boat, his eyes are turned from the Savior. The wind is boisterous. The waves roll high, and come directly between him and the Master; and he is afraid.
For a moment Christ is hidden from his view, and his faith gives way. He begins to sink. But while the billows talk with death, Peter lifts his eyes from the angry waters, and fixing them upon Jesus, cries, “Lord, save me.” Immediately Jesus grasps the outstretched hand, saying, “O thou of little faith, wherefore didst thou doubt?” Walking side by side, Peter's hand in that of his Master, they stepped into the boat together. But Peter was now subdued and silent. He had no reason to boast over his fellows, for through unbelief and self-exaltation he had very nearly lost his life. When he turned his eyes from Jesus, his footing was lost, and he sank amid the waves.
Matthew 14:29 And he said, Come. And when Peter was come down out of the ship, he walked on the water, to go to Jesus. 30 But when he saw the wind boisterous, he was afraid; and beginning to sink, he cried, saying, Lord, save me. 31 And immediately Jesus stretched forth his hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?
May God add His blessing to the study and practice of His word. "Good night" and God bless!
