Matthew 14:31

And immediately Jesus stretched forth His hand, and caught him, and said unto him, O thou of little faith, wherefore didst thou doubt?

Peter was always impetuous, quicker to act than to think. The voice of the Lord filled him with a courage that made him almost reckless. It was the joy of faith that made him cry out to the Lord. He wanted to be the first to grasp the Lord by the hand. And following the assuring invitation of Christ, he actually stepped out of the boat and walked on the water towards Jesus. As long as the eyes of his faith as well as his physical eyes were directed toward his Lord and Master, everything went well. But an unusually strong gust of wind, an exceptionally high wave, caused him to falter; his faith wavered; he began to sink. He no longer trusted in the word of assurance that had been given him. But in this emergency he cries to the Master, whom he still knows to be the Lord of the universe. And the patient kindness of Jesus saves him. He quickly caught him and held him above the water, not, however, without chiding him for his weakness of faith, which caused him to doubt at the critical moment. The Lord has patience with the weakness of those that are His own; He hears their crying; He holds them up even in the hour of death with His strong arm.
