Perhaps you have heard someone say, "He must be a real Christian; it shows in his face." Some explain it as a glow, a light, a warmth. They glimpse the spiritual radiance of a reverent life and feel the power of fervent, unceasing prayer.
This glow which men see and the spiritual power they feel are the effects of the radiation of God, divine Love, in lives which are actually the very expression of Love. Even the smallest degree of spiritual understanding brings some light into human consciousness. Since the real, spiritual man is the expression of God, infinite Mind, he forever shows forth divine light and expresses divine energy and power.
In (Science and Health with Key to the Scriptures, p. 504), "This light is not from the sun nor from volcanic flames, but it is the revelation of Truth and of spiritual ideas." Through the irradiation of God, we see the unfoldment of that which already is—the spiritual nature of creation, man and the universe. Is it any wonder that one who is learning the truths of God and man radiates health, strength, energy, and love?
