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.See this passage explained in the notes at Matthew 14:22-36.51. And he went up unto them into the ship—John (Joh 6:21) says, "Then they willingly received him into the ship"—or rather, "Then were they willing to receive Him" (with reference to their previous terror); but implying also a glad welcome, their first fears now converted into wonder and delight. "And immediately," adds the beloved disciple, "they were at the land whither they went," or "were bound." This additional miracle, for as such it is manifestly related, is recorded by the fourth Evangelist alone. As the storm was suddenly calmed, so the little bark—propelled by the secret power of the Lord of nature now sailing in it—glided through the now unruffled waters, and, while they were wrapt in wonder at what had happened, not heeding their rapid motion, was found at port, to their still further surprise.

"Then are they glad, because at rest

And quiet now they be;

So to the haven He them brings

Which they desired to see."

Matthew (Mt 14:33) says, "Then they that were in the ship came [that is, ere they got to land] and worshipped him, saying, Of a truth Thou art the Son of God." But our Evangelist is wonderfully striking.

and the wind ceased and they were sore amazed in themselves beyond measure, and wondered—The Evangelist seems hardly to find language strong enough to express their astonishment.

See Poole on "Mark 6:47"

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.

And he went up unto them into the ship; and the wind ceased: and they were {y} sore amazed in themselves beyond measure, and wondered.

(y) They were still so amazed when they knew that it was no spirit, that they were much more astonished than they ever were before, when they saw the wind and the sea obey his commandment.
