Every good gift and every perfect gift is from above, and comes down from the Father of lights, with whom is no ficklenss…
God, as the Author of all our spiritual light, receives a faint illustration from the sun, as the source of natural light. The rays from the sun are of three kinds, differing from one another probably only as to the lengths of the waves of which they are composed.
1. Light rays. Nearly all the light we receive comes from the sun. Even the moonlight is but reflected sunlight. Even when we are in the shade, or in the house where we cannot see the sun, the light we receive is sunlight, dispersed from the particles in the air, reflected from all things around us; even the light of our lamps and gas-burners is but sunlight which has been stored up in the earth. So it is that all our spiritual light, from whatever sources it seems to come, is really from God. Our white sunlight is really composed of thousands of colours, shades, and tints, which fill the world with beauty. Such variety is in the pure light from God, reflected from our manifold natures, needs, and circumstances.
2. Heat rays. Nearly all the heat in the world comes directly or indirectly from the sun. The fires that warm us and that are the source of power are from the wood or coal in which the heat of the sun has been stored. Such is God's love to us.
3. Chemical rays, which act upon plants and cause the movements of life. These rays are in a sense the source of life, the instrumentality of life. So God is the Source of our spiritual life. Light, love, and life all come from the Father of lights.
