Read Genesis 1:1-5
In the beginning, when God created the universe,a 2the earth was formless and desolate. The raging ocean that covered everything was engulfed in total darkness, and the Spirit of Godb was moving over the water. 3Then God commanded, “Let there be light”—and light appeared. 4God was pleased with what he saw. Then he separated the light from the darkness, 5and he named the light “Day” and the darkness “Night”. Evening passed and morning came—that was the first day.
When God speaks - the whole universe comes into order. Inseparable things like light and darkness are divided up.
You are the God who speaks - free me to be obedient.
