Genesis 1:3 - 5
3 And God said, "Let there be light," and there was light.
4 God saw that the light was good, and He separated the light from the darkness.
5 God called the light "day," and the darkness he called "night." And there was evening, and there was morning—the first day.
Most of us know the story or the creation like the back of our hand. However, a recent perusal led to a discovery. Verse 1 says "In the beginning God created the heavens and the earth." So the first thing that God created was the heavens and then the earth. Verse 2 says "Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters." The earth was formless and empty. Does it mean that God created a formless earth and made it empty? And it continues to say that the Spirit of the God was hovering over the waters. There was no mention about God creating the waters but the heavens and the earth. Secondly, the Spirit of God was hovering over the place where it was formless and empty. And all this is not included in the first day because verse 5 says "... And there was evening, and there was morning - the first day." So I believe that there should be a million years between the first and the second verse.
Now God sees that the earth He had created was formless and empty and was filled with darkness. So God creates light and calls it day and the existing darkness, He calls the night. Now remember, the Sun is not yet created. It is created only in the fourth day as verse 16 says "God made two great lights—the greater light to govern the day and the lesser light to govern the night. He also made the stars." Scientists or physicists discovered that because of the Sun we have day and the absence of the Sun we have night. However, the Bible claims that even before the Sun was created, God created the light and He separated the light from the darkness. I believe that there is a greater light than the Sun and the greater light was created even before the Sun. And the source for this light is unknown. Only after creating this light, God creates the rest of the creation i.e., only in the light of this light did God create the rest. For verse 5 says how the first day is ended "God called the light "day," and the darkness he called "night." And there was evening, and there was morning—the first day." I believe that because of this light was there day (morning) and night (evening) and then day (morning).
What is this light that is greater than the lights mentioned in verse 16? On comparing with John 1st chapter, I believe that this Light is none other than Jesus Christ himself. He was the first creation and through Him all the things were created. John 1:9 says "The true light that gives light to every man was coming into the world." This proves that the Light is Christ himself. The question is "Do we have this Light in us?" When we have this light, there shall be no darkness (John 1:5).
