Luke 5:3

And he entered into one of the boats, which was Simon's, and asked him to put out a little from the land. And he sat down and taught the multitudes out of the boat. And when he had left speaking, he said unto Simon, Put out into the deep, and let your nets down for a draught.

Put out into the deep ... The KJV has "Launch out into the deep"; and Jesus would follow up this command, intended to be obeyed literally, with another just like it in the spiritual sector when he invited them to "follow." Their acceptance of the call was a launching out into the deep on a far grander scale than anything they could have done in Peter's boat. Every Christian and all churches still need this commandment to "put out into the deep." The miracle here is unique to Luke.
