Psalm 139:11-12
If I say, "Surely the darkness will hide me and the light become night around me," even the darkness will not be dark to you; the night will shine like the day, for darkness is as light to you.
This is physical light and darkness. God made light (Genesis 1:3-5), separating what was light from what was not light, or darkness. Then He made the "light-holders" (Genesis 1:14-19) to shine in our sky and delineate days, months, seasons and years, so we could keep time. So the light is what God made, and the darkness is the absence of light; but they're both the same to Him; He sees me and holds my hand regardless of whether I'm in the day or the night. He is always there to take care of me, I need never fear, His love holds me.
Even so, come, Lord Jesus!
