John Gill Bible Commentary

And his disciples came unto him,.... From some other part of the ship, being in great consternation, and distress, and awoke him; saying, Lord, save us, we perish. They awoke him by their loud cries, and repeated calls; for in Luke, the form of address is doubled, "Master, Master!" expressing their distress, importunity, and haste for deliverance saying, "save us, we perish", or "we are lost": which shows the apprehensions they had of their condition; not only that they were in danger of being lost, or were ready to be lost, but were lost: they saw no probability of escaping by any natural, rational methods: wherefore they apply to Christ, believing that he was able to save them, in this their extremity; as they had indeed a great deal of reason to conclude, from the miracles they had that day seen performed by him.
