To an unscientific viewpoint, the dawn might appear to be caused by the light of the sun getting brighter or by the darkness being driven back. The first would imply that the intensity of the sun's light is variable. The second would give priority to darkness, making it a self-existent entity that has within itself the power to resist light, and that must first be subdued before light can be admitted. Thanks to astronomical science, we do not believe that the sun's light really grows brighter, nor do we accept the notion that darkness has any innate power.
To natural science, dawn is the result of the earth's gradual movement into the unvarying light of the sun. According to Christian Science, healing results from the submission of human thought to the eternal light of God, or Mind. This divine light is universal and self-existent, and it is fully expressed in man's true selfhood as God's spiritual image.
Human experience, with its mixture of good and evil, expresses an imperfect sense of God and man, darkened by belief in God's absence or opposite. It only hints at the substance of spiritual reality, or real substance. Yet the good in human experience is evidence of God's presence, of that which is enduring in our lives. Mrs. Eddy writes reassuringly: "All that is beautiful and good in your individual consciousness is permanent. That which is not so is illusive and fading." Unity of Good, p. 8.
