In the beginning God created the heavens and the earth. The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters. Then God said,"Let there be light"; and there was light. And God saw the light, that it was good; and God divided the light from the darkness.
What a beautiful picture of the power of God! God comanded let ther be light and light obeyed! Our creator divided the light from the darkness from the very beginning and it's a perfect blueprint of how to walk. There is always a distinction between light and dark, good and evil. The separation begins on the very first day!
