Matthew 14:28

28.And Peter answering. The condition which he lays down shows that his faith was not yet fully settled. If it is thou, says he, bid me come to thee on the water. But he had heard Christ speak. Why then does he still argue with himself under doubt and perplexity? While his faith is so small and weak, a wish not well considered bursts into a flame. He ought rather to have judged of himself according to his capacity, and to have supplicated from Christ an increase of faith, that by its guidance and direction he might walk over seas and mountains. But now, without the wings of faith, he desires to fly at will; and though the voice of Christ has not its due weight in his heart, he desires that the waters should be firm under his feet. And yet there is no room to doubt that this longing sprung from a good principle; but as it degenerates into a faulty excess, it cannot be applauded as good.

Hence too it happens that Peter immediately begins to smart for his rashness. Let believers, therefore, instructed by his example, beware of excessive haste. Wherever the Lord calls, we ought to run with alacrity; but whoever proceeds farther, will learn from the mournful result what it is to overleap the bounds which the Lord has prescribed. Yet it may be asked, Why does Christ comply with Peter’s wish? for by so doing he seems to approve of it. But the answer is obvious. In many eases God promotes our interests better by refusing our requests; but at times he yields to us, that by experience we may be the more fully convinced of our own folly. In this manner, it happens every day that, by granting to those who believe in him more than is actually needed, he trains them to modesty and sober-mindedness for the future. Besides, this was of advantage to Peter and to the other disciples, and it is of advantage to us at the present day. The power of Christ shone more brightly in the person of Peter, when he admitted him as a companion, than if he had walked alone on the waters. But Peter knows, and the rest see plainly, that, when he does not rest with a firm faith, and rely on the Lord, the secret power of God, which formerly made the water solid, begins to disappear; and yet Christ dealt gently with him by not permitting him to sink entirely under the waters. (382) Both of these things happen to us; for as Peter was no sooner seized with fear than he began to sink, so the fleeting and transitory thoughts of the flesh immediately cause us to sink in the midst of our course of employments. (383) Meanwhile, the Lord indulges our weakness, and stretches out his hand, that the waters may not swallow us up altogether. It must also be observed that Peter, when he perceives the unhappy and painful consequences of his rashness, betakes himself to the mercy of Christ. And we too, though enduring just punishment, ought to betake ourselves to him, that he may have compassion on us, and bestow the aid of which we are unworthy.
