That is a beautiful illustration, it seems to me, that does not want any opening up; you can all make the application of it to the Lord Jesus for yourselves. As Dr. Watts sings—

In the darkest shades if he appear,

My dawning is begun;

He is my soul's sweet morning star,

And he my rising sun.

Then we begin to put on all sorts of beauty, as the leaves are painted by the rays of the sun. We owe every atom of color that there is in any of our virtues, and every trace of flavor that there is in any of our fruits, to those bright sunbeams that come streaming down to us from the Sun of Righteousness, who carries many other blessings besides healing beneath his wings.

The effect of the sun upon vegetation can be observed among the flowers in your own garden. Notice how they turn to him whenever they can; the sunflower, for instance, follows the sun's course as if he were himself the sun's son, and lovingly looked up to his father's face. He is very much like a sun in appearance, and I think that is because he is so fond of turning to the sun. The innumerable leaves of a clover field bend toward the sun; and all plants, more or less, pay deference to the sunlight to which they are so deeply indebted. Even the plants in the hothouse, you can observe, do not grow in that direction you would expect them to do if they wanted warmth, that is, toward the stovepipe, whence the heat comes, nor even to the spot where most air is admitted; but they will always, if they possibly can, send out their branches and their flowers toward the sun. That is how we ought to grow toward the Sun of Righteousness; it is for our soul's health that we should turn our faces toward the Sun, as Daniel prayed with his windows open toward Jerusalem. Where Jesus is, there is our Sun; toward him let us constantly incline our whole being.

Not very long ago I met with the following remarkable instance of the power of rays of light transmitted from the sun: some divers were working at Plymouth Breakwater; they were down in the diving-bell, thirty feet below the surface of the water; but a convex glass, in the upper part of the bell, concentrated the sun's rays full upon them, and burned their caps. As I read this story, I thought it was a capital illustration of the power there is in the gospel of our Lord Jesus Christ. Some of our hearers are fully thirty feet under the waters of sin, if they are not even deeper down than that; but, by the grace of God, we will yet make them feel the blessed burning power of the truths we preach, even if we do not succeed in setting them all on fire with this powerful glass. Perhaps, when you were a boy, you had a burning-glass, and when you were out with a friend who did not know what you had in your pocket, while he was sitting very quietly by your side, you took out your glass, and held it for a few seconds over the back of his hand until he felt something rather hot just there. I like the man who, in preaching, concentrates the rays of the gospel on a sinner till he burns him. Do not scatter the beams of light; you can turn the glass so as to diffuse the rays instead of concentrating them; but the best way of preaching is to focus Jesus Christ, the Sun of Righteousness, right on a sinner's heart. It is the best way in the world to get at him; and if he is thirty feet under the water, this burning-glass will enable you to reach him; only mind that you do not use your own candle instead of the Sun, for that will not answer the same purpose.

Sometimes the sun suffers eclipse, as you know. The moon intrudes between us and the sun, and then we cannot see the great orb of day. I suppose we have all seen one total eclipse, and we may see another. It is a very interesting sight; but it appears to me that people take a great deal more notice of the sun when he is eclipsed than they do when he is shining clearly. They do not stand looking at him, day after day, when he is pouring forth his bright beams in unclouded glory; but as soon as ever he is eclipsed, then they are out in their thousands, with their glasses, and every little boy in the street has a fragment of smoked glass through which he watches the eclipse of the sun.

Thus, brethren, I do not believe that our Lord Jesus Christ ever receives so much attention from men as when he is set forth as the suffering Saviour, evidently crucified among them. When the great eclipse passed over the Sun of Righteousness, then all eyes were fixed upon him, and well they might be. Do not fail to tell your hearers continually about that awful eclipse on Calvary; but mind that you also tell them all the effects of that eclipse, and that there will be no repetition of that stupendous event.
