That means light enables us to see God through his creation. Without light we would not be able to see the colors and beauty of the physical world.
Secondly, light makes everything God has created visible. That means that all food has its source through light since all life is dependent in some way on food from plants (i.e., Animals eat animals that eat plants.). Besides producing the warmth that is needed to sustain life, light is essential to the process of photosynthesis, which enables plants to produce the food they need to live and grow. We’ve already seen that light is necessary for life, so the first purpose of light is to provide for physical life. We also need to recognize that light exists in both the physical and spiritual realms. We need to understand the design of light and just how good and purposeful light is. When God says that something is good that means it fulfills the purpose for which he designed it. After bringing forth light, God saw that the light he made was good.God brought forth the light which is essential for life.First God created the heavens or the space in which he would put the things he made and the basic matter of which things would be made.Let’s stop and think about what the first three verses of Genesis say existed in creation during the first day. Whatever he did, he did it by the power of his word and the nature of who he is. When God said, “Let there be light,” it would seem he excited the atoms that he had created by putting energy into his creation, causing atoms to absorb energy and release light. As they de-excite they give off photons which make up visible light and other electromagnetic waves. Once excited atoms tend to want to de-excite, to go back to the condition they were in. An easy way to excite atoms is to heat them up. Atoms become excited by absorbing light from another source or being struck by other particles, which pass on energy. Light is produced when atoms gain extra energy and enter what is called an “excited” state. 5God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning–the first day. 4God saw that the light was good, and he separated the light from the darkness. Genesis 1:3-5 describes how God created light: 3And God said, “Let there be light,” and there was light. Once God had established the basic building blocks of creation, he spoke light into existence.
