22 Immediately after this, Jesus insisted that his disciples get back into the boat and cross to the other side of the lake, while he sent the people home. 23 After sending them home, he went up into the hills by himself to pray. Night fell while he was there alone. 24 Meanwhile, the disciples were in trouble far away from land, for a strong wind had risen, and they were fighting heavy waves. 25 About three o'clock in the morning Jesus came toward them, walking on the water. 26 When the disciples saw him walking on the water, they were terrified. In their fear, they cried out, "It's a ghost!" 27 But Jesus spoke to them at once. "Don't be afraid," he said. "Take courage. I am here! " 28 Then Peter called to him, "Lord, if it's really you, tell me to come to you, walking on the water." 29 "Yes, come," Jesus said. So Peter went over the side of the boat and walked on the water toward Jesus. 30 But when he saw the strong wind and the waves, he was terrified and began to sink. "Save me, Lord!" he shouted. 31 Jesus immediately reached out and grabbed him. "You have so little faith," Jesus said. "Why did you doubt me?"

Commentary on Matthew 14:22-33
(Read Matthew 14:22-33)
Those are not Christ's followers who cannot enjoy being alone with God and their own hearts. It is good, upon special occasions, and when we find our hearts enlarged, to continue long in secret prayer, and in pouring out our hearts before the Lord. It is no new thing for Christ's disciples to meet with storms in the way of duty, but he thereby shows himself with the more grace to them and for them. He can take what way he pleases to save his people. But even appearances of deliverance sometimes occasion trouble and perplexity to God's people, from mistakes about Christ. Nothing ought to affright those that have Christ near them, and know he is theirs; not death itself. Peter walked upon the water, not for diversion or to boast of it, but to go to Jesus; and in that he was thus wonderfully borne up. Special supports are promised, and are to be expected, but only in spiritual pursuits; nor can we ever come to Jesus, unless we are upheld by his power. Christ bade Peter come, not only that he might walk upon the water, and so know his Lord's power, but that he might know his own weakness. And the Lord often lets his servants have their choice, to humble and prove them, and to show the greatness of his power and grace. When we look off from Christ, and look at the greatness of opposing difficulties, we shall begin to fall; but when we call to him, he will stretch out his arm, and save us. Christ is the great Saviour; those who would be saved, must come to him, and cry to him, for salvation; we are never brought to this, till we find ourselves sinking: the sense of need drives us to him. He rebuked Peter. Could we but believe more, we should suffer less. The weakness of faith, and the prevailing of our doubts, displease our Lord Jesus, for there is no good reason why Christ's disciples should be of a doubtful mind. Even in a stormy day he is to them a very present help. None but the world's Creator could multiply the loaves, none but its Governor could tread upon the waters of the sea: the disciples yield to the evidence, and confess their faith. They were suitably affected, and worshipped Christ. He that comes to God, must believe; and he that believes in God, will come, Hebrews 11:6.
