Why would God make the start of the day at night? We usually equate night with the ending, evil and death. Yet the Bible begins with darkness. Our lives begin in the darkness of the womb. Inspiration often comes during the night. And Christianity comes to the sinner, lost in darkness.
Maybe life is like the womb that offers nourishment; where the foundation of what we will become is being laid. We depend on our mothers to provide us with nourishment and the life we need to survive; though, we may not realize or appreciate it. We often struggle against the confines of the womb, kicking and punching. We suffer some of the pains we will experience in life. Then we experience the pain of being born, when our skull is crushed and we are pushed through that small opening of the cervix. Yet the greater work, the greater pain, is always done and felt by the mother, just as God does the greater work and felt the greater pain for us.
Maybe night is when God is doing a greater work in us. Often it is in the dark of night that God fills our minds and hearts with creative inspiration. How many problems find their resolution on waking in the morning? We find our lives to be full of problems. We feel lost in darkness with no way out. Then God, who has hovered over our lives since our conception, brings light into our lives and moves us from the night of sin to the day of His salvation.
The natural is a perfect reflection of the supernatural, and death seems to just move us from the womb of this earth to our new life in heaven. What a reward the darkness of death brings. Yes, the new day starts with the beginning of night, just as God ordained.
