Verses 51, 52. - The amazement of the disciples was very great. Nor was the impression confined to them alone. St. Matthew (Matthew 14:33) tells us that they who were in the boat came and worshipped him. They felt, at least for the 'moment, that they were brought into awful nearness to One whose "way is in the sea," and whose "path is in the great waters," and whose "footsteps are not known." They needed not, however, to have been so amazed, for they had just witnessed his power in the miracle of the loaves; but they understood not (ἐπὶ τοῖς ἄρτοις) concerning the loaves, but their heart was (πεπωρωμένη) hardened; literally, stupefied and blinded.

6:45-56 The church is often like a ship at sea, tossed with tempests, and not comforted: we may have Christ for us, yet wind and tide against us; but it is a comfort to Christ's disciples in a storm, that their Master is in the heavenly mount, interceding for them. And no difficulties can hinder Christ's appearance for his people, when the set time is come. He silenced their fears, by making himself known to them. Our fears are soon satisfied, if our mistakes are set right, especially our mistakes as to Christ. Let the disciples have their Master with them, and all is well. It is for want of rightly understanding Christ's former works, that we view his present works as if there never were the like before. If Christ's ministers now could cure people's bodily diseases, what multitudes would flock after them! It is sad to think how much more most care about their bodies than about their souls.And he went up unto them in the ship,.... That is, after Peter had desired he might be bid to come to him upon the water, and having got leave, made an essay; but the wind being boisterous, and beginning to sink, he cried out for help; when Christ stretched out his hand, and saved him; and then he, together with Peter, went up into the ship to the rest of the disciples, as is related by Matthew, Matthew 14:28, though omitted by this evangelist:

and the wind ceased; from blowing; it was laid at once, as soon as ever Christ entered the ship:

and they were sore amazed in themselves beyond measure, and wondered. The Ethiopic version adds, "at him"; they were astonished, when they found it was Christ, and not a spirit; and they were more amazed at his walking upon the sea; and they marvelled still more abundantly, when they observed that the wind ceased upon his coming into the ship; their amazement was beyond expression, and therefore many words are made use of to signify it by.
