Studies in Genesis 1
And God made the two great lights — the greater light to rule the day and the lesser light to rule the night — and the stars. And God set them in the expanse of the heavens to give light on the earth, to rule over the day and over the night, and to separate the light from the darkness. (Genesis 1:16-18 ESV)
Our universe, the universe which God created and in which we exist and live, is filled with real, physical places. Though no one will ever see these places they exist and move according to the universal laws of nature dictated by God. His laws are not different, nor work differently, from one place in the universe to another. They are the same throughout.
Heaven is just as real as the universe. It is a place not defined by physical laws but by spiritual laws. As with the physical universe God determines and dictates the spiritual laws of eternity. Just as the physical universe shows the evidence of God’s handiwork so the physical laws shows the evidence of the spiritual laws of eternity. Yet, we cannot test and prove the spiritual laws of eternity as we can the physical laws. We must rely upon God’s special revelation for our information about eternity. He does not answer the thousands of questions we have.
Eternity is outside of time and has no physical boundaries. There are no days in eternity. Light in eternity comes from God. Yet, there is darkness. There is in eternity a real place filled with darkness. Hell is a real place governed by the spiritual laws of God which govern eternity.
Even in eternity God separates light from darkness. We are told in Scripture, that God judges those who rebel against Him, those who are “cursed”, which means tried, convicted and sentenced for crimes against God. Their sentence is eternal separation from Him. “Then he will say to those on his left, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels’” (Mat 25:41 ESV).
It is the fourth day. God has created life. Yet, there is a hint of death in creation, found in the separation of light from darkness. His purpose transcends the physical and fills the eternal.
