Jesus concealed something. Laughter perhaps?

Chesterton ends his Orthodoxy with a curious thought on Jesus and his personality as portrayed in the Bible. Others have touched upon this before. It warms me to think of it. Perhaps the scriptures could have used a little more of this (read on). I guess he knew what he was doing though.

The tremendous figure which fills the Gospels [Jesus], towers above all the thinkers who ever thought themselves tall. His pathos was natural, almost casual. The Stoics, ancient and modern, were proud of concealing their tears. He never concealed His tears; He showed them plainly on His open face at any daily sight, such as the far sight of His native city. Yet He concealed something. Solemn supermen and imperial diplomatists are proud of restraining their anger. He never restrained His anger. He flung furniture down the front steps of the Temple, and asked men how they expected to escape the damnation of Hell. Yet He restrained something. I say it with reverence; there was in that shattering personality a thread that must be called shyness. There was something that He hid from all men when He went up on a mountain to pray. There was something that He covered constantly by abrupt silence or impetuous isolation. There was some one thing that was too great for God to show us when He walked upon the earth; and I have sometimes fancied that it was His mirth.
