John 2 - G. Campbell Morgan's Exposition on the Whole Bible

At Cana our Lord wrought what John describes as the "beginning of His signs." It was a sign of power in the realm of creation, and of it being exercised in answer to faith. It was a sign, moreover, of His attitude toward pure joy in the activities of human life.

After a short period of retirement at Capernaum, Jesus went to Jerusalem, and there gave the first outward sign of His official position. The outer courts of the Temple had been turned into a veritable market-place. He cleansed them, and when asked for His authority, in words not then probably understood, He declared that the final sign of such authority would be His death and resurrection. Such an action by our Lord was bound to draw attention to Him. Moreover, while in Jerusalem He wrought other signs, so that many were attracted to Him. It is an arresting fact that whereas, in that sense, they committed themselves to Him, He, knowing them perfectly, did not commit Himself to them.
