We Understand the Importance of Light
by Maryann Ziemer
We absolutely need light. We cannot function completely in the dark. We cannot live nor thrive without light. Light is a form of energy, originating in the seething activity of the sun. The light of the sun travels through cold, dark space, reaching the earth in various energy levels, from gamma rays to visible light rays to infrared.
Human beings have discovered many ways to use
the various energy levels of light. X-rays reveal our bones for medical
purposes. Microwave energy cooks food quickly for our convenience.
Radio waves help us communicate across long distances. And it is
through the energy of visible light waves that Easter lilies grow and
wheat crops flourish.
Talk about: Visible light waves make
possible our gift of sight. Without light, we cannot see. Close your
eyes and all is dark. Injure or destroy the eye’s ability to receive
and process light energy, and the sense of sight is gone. It is through
light—reflected from objects and entering our eyes through a wondrous,
instantaneous, God-given process of biochemical and bioelectrical
signals—that we see objects, the colors of the universe, the world
around us.
