And this rainbow is all of one colour, a clear, soft emerald-green. We know that green is the most restful of all colours. Some colours are irritating. Some persons of very sensitive, nervous temperament are even made sick by certain colours. And we are all affected more than we know in a hurtful way by certain colours. But green is the colour of rest. It soothes the eyes and nerves and even the spirit. The rainbow round about the throne looked like a quiet, quieting emerald-green. The One on the throne is at perfect rest regarding things down here. He knows all. His ears hear all, the cry of distress and despair, the defiance and arrogance and blasphemy. His eyes see His children down here, creative children all of them, prodigal children so many of them, and trusting children walking in the shadows. He sees all. And He feels all with His great feeling heart. Yet He is at rest. Do you wonder how He can be? When Jesus saw the multitudes He was moved with compassion; He suffered in heart with them, for they were as shepherdless sheep, torn and distressed. And the heart beating in rhythm with His has as hard a time as He. If He lead you in service to some foreign mission land, you see and know and feel as no tourist party hurried through the outer fringes ever does or can. And in Christian lands of the West, and the homeland, in slum as in polite circles, in commercial quarters as in the university world, the heart that is in touch with Jesus' heart sees and hears and feels and senses things as they are under the surface or sticking boldly out through the surface. And feels at times as though it can never again be at rest. How can He, on the throne, be so quiet, and be at rest? And there is an answer to our burning question, a simple, real answer. _He knows the end._ He has a purpose and a plan. The present is only one stage in His great plan. This is man's opportunity, and possibly some one's else opportunity, too. It is to be followed by something else radically different down on this earth. He is held steady during this time by a great purpose. It is a purpose of great, tender love. To His eye looking sleeplessly down there is rest even as of emerald-green. And so there will be rest for him who looks sleeplessly _up_ to the _throne_ of control, encircled in the emerald rainbow of perfect peace. And we can be of best service to Him by resting in our hearts, resting in Him, even while working in the thick of things as they are down here. They See His Face. Then John sees twenty-four other thrones round about the central throne. And on these there are twenty-four men sitting. These men are wearing white garments, and have crowns of gold upon their heads. This is the part of intense interest. Who are these? And what does this mean?
