Another quality that pertains to the nature of light is that it is revealing. Darkness obscures. Where it is not light, a pit may gape at our feet, a murderer may be waiting in our path, a dagger aimed at our heart; we do not see and know, our vision is held. It requires light to perceive these things. And so in the spiritual world, Christ is the great Revealer. By Him we come to know God and our true selves. By Him we learn who and where we are, what our needs are, and how to relieve them. One of the hardest things in the world is to make people believe that they are guilty and lost beings. The reason is, they are in the dark. They need the light to show them themselves. And that light is Christ. Only let a man examine himself in the light of Christ's life and teaching, and it will not be long until he sees that self of his to be a mere mass of guilt, and things appearing quite differently in this world of imperfection and sin. And to mention the final feature, light is life-giving. Without light the world is dead. Where the sun rarely shines, or not at all, there is barrenness, dreariness, perpetual winter, desolation. It is the warming light of spring that starts the dormant germs, that swells the buds, and clothes the vineyards, the field, and the woods with vegetation, fragrance, and plenty. So with the spiritual Light. Where Christ is not, life is not, there is spiritual barrenness, winter upon the soul. But when His beams shine in upon the soul, the seeds of virtue put forth, the tree of faith lifts up its fragrant bloom, and the fruits and flowers of love and grace spring and bud. Thus, by a few comparisons with the material, natural light, have we sought to explain in what sense Christ is called, or rather calls Himself, the Light.
