Who is this? What a very strange question to ask after all that they had already seen. When they saw water changed to wine, the blind seeing, and bread multiplied, they thought they knew who Jesus was. But when they were delivered from death it dawned on them that they had missed entirely on who they were sailing with.
When Jacob asked, he was not told.
When Moses asked God said , “I am!”
When the disciples asked Jesus brought them safely to the other side of the sea.
Who is this to you and me? He is the master of any storm, Alpha and Omega and the Good Shepherd who gives His life for His sheep!
