In the beginning, God created the heavens and the earth. The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. And God said, “Let there be light,” and there was light. And God saw that the light was good. And God separated the light from the darkness. God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day.
Genesis 1:1-5 ESV
God is the Creator of all things, Heaven, space, planets, stars, animals, mankind. But one thing to note here is the phrase “In the beginning,” this is in reference to the beginning of God’s creation, not the beginning of God. We are creatures (created beings) and we live in His creation (created things), because of this we all have a beginning, a point where we can first recognize existence. But God who is eternal does not have beginning or end, this is due to the fact that God is not constrained to time, rather time itself is a very creation of the Almighty God.
God had created the earth but it still lacked form. It was void of God. The Spirit of God hovered over the waters of the earth during this time but it still lacked, so God spoke forth light and there was light. So far we can recognize in this the person of the Holy Trinity. The Father who orchestrates all things together with His Holy Spirit which is present amidst all of Creation and the Son who is the Word and the light of God (John 1:14). Together the Holy Trinity created everything in existence and they have worked in company with one another in all things.
When God speaks forth light, we recognize that (John 1:14) Jesus is the Word of God made flesh and the light of the world in which all men come to God. (Isaiah 45:7) God separated day and night or rather He made a distinction between the two.
It is almost as if He set apart the day to be covered in the provision of His heavenly light. And at night He withholds this same light as to show creation it’s need and dependence on the light of God’s provision. This night does not keep people away from God, but rather it shows people their own darkness and sin so that they would come to love and appreciate the God that provides the light rather than grow hardened and cold towards the things of God.
(John 1:9-13) Mankind must recognize their sinfulness so that mankind can recognize their need for salvation by the conviction of the Holy Spirit so that they can come to stand before the Father justified through the sacrifice of the Son.
