48 And seeing that they had trouble in getting their boat through the water, because the wind was against them, about the fourth watch of the night he came to them, walking on the sea; and he would have gone past them; 49 But they, when they saw him walking on the sea, took him for a spirit, and gave a loud cry: 50 For they all saw him, and were troubled. But straight away he said to them, Take heart, it is I, have no fear.
Matthew Henry's Commentary on Mark 6:48-50
Commentary on Mark 6:45-56
(Read Mark 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.
