John Chrysostom

If any should say, that this was a sign of no small faith to go and rouse Jesus; it is rather a sign that they had not a right opinion concerning Him. They knew that when wakened He could rebuke the waves, but they did not yet know that He could do it while sleeping. For this cause He did not do this wonder in the presence of the multitudes, that they should not be charged with their little faith; but He takes His disciples apart to correct them, and first stills the raging of the waters. Then he arose, and rebuked the winds and the sea, and there was a great calm.
