The inscription on Eddystone lighthouse is, "To give light and to save life." This is a motto that also may be used to show the purpose of our Saviour Jesus Christ. He came to give light and to impart life. We erect a lighthouse on rocks that have been proved to be dangerous to life — we put it on the rocks — and, likewise, when souls were wrecked by the corruption of human nature, the Light of the world shone from the human nature of Christ Jesus. His sacred light warns us from the sin and corruption that have been proved to be so fatal to the peace and life of human souls; and, like a lighthouse, it also shows the safe path to the harbour of heaven. God is Light; and the body of Jesus is the lighthouse from which the fulness of the Almighty shone forth on a dying world. The sun is spoken of as an angel with healing in its wings. You may not be aware that persons who live in a room which opens only to the north, are more in danger of sickness than if they lived in a room which faced the opposite point of the compass. Statistics tell us that the unsunned rooms of a barracks or hospital are much less healthful than those parts on which the sun shines through the day. It is said that the absence of the direct rays of the sun increases the mortality twenty percent, as compared with the places on which it shines continually. The sun is our best doctor and sunshine is our cheapest and most efficient physic. Narrow streets, blind alleys, and back slums in which the rays of the sun never shine are a disgrace to our humanity. In such places you see, like as you see in that part of your garden on which the sun does not shine, stunted and diseased human plants. If you give the people wide streets and good houses, and provide three times the number of gaslights at night, you will have a more healthful and a more holy city than we have just now. The sun shines away disease, and a powerful light scares away sin.
