24. The ship was now in the midst of the sea. The reader will find this narrative expounded by me at the sixth chapter of John’s Gospel, and therefore I shall treat it more briefly here. When Christ permitted his disciples to be tossed about in a perilous condition, for a time, by an opposing storm, it was to fix their attention more powerfully on the assistance which he brought to them. For the adverse wind arose about midnight, or at least a little before it, and Christ appears about the fourth watch, that is, three hours before sunrise. Their arms were not more fatigued by rowing than their faith was shaken by grievous terrors. But when they were urged by strong necessity to desire the presence of their Master, it showed very extraordinary stupidity to be alarmed at his appearance as if he had been a ghost.
For this reason Mark tells us, that their heart was blinded, and that they understood not about the loaves; for that miracle had given abundant evidence that Christ possessed divine power to assist his followers, and that he was careful to assist them, when necessity required. Justly, therefore, are they now charged with stupidity in not immediately recollecting that heavenly power, having beheld, on the preceding day, so astonishing a proof of it, which ought to have been still before their eyes. It is, no doubt, true, that their blameworthy slowness of apprehension was the reason why they were astonished; for they had not profited, as they ought to have done, by other and preceding miracles. But the principal charge brought against them is blindness, in allowing so recent an exhibition to fade from their memory, or rather in not directing their mind to the contemplation of Christ’s divinity, of which the multiplication of the loaves was a sufficiently bright mirror.
Two things are expressed by the words of Mark; first, that they did not properly consider the glory of Christ, which was exhibited in the multiplication of the loaves; and, secondly, a reason is assigned, that their heart was blinded. This appears to have been added, not only as an aggravation of their fault, but as a warning to us respecting the corruption of our understanding, that we may seek from the Lord new eyes. It certainly was a proof—as I have lately mentioned—of brutal ignorance, that they did not perceive the power of God, when they might almost feel it with their hands; but as the whole human race labors under the same disease, Mark purposely mentions blindness, in order to inform us that it is no new thing if men have their eyes closed against the manifest works of God, till they are enlightened from above; as Moses also said,
The Lord hath not yet given thee a heart to understand, (Deuteronomy 29:4.)
Now though the word heart more frequently denotes the will or the seat of the affections, yet here, as in that passage which I have now quoted from Moses, it is put for the understanding.
