Job 38:16-20 Have you entered into the springs of the sea? or have you walked in search of the depths? Have the gates of death been revealed to you? or have you seen the doors of the shadow of death? Have you perceived the breadth of the earth? declare if you know it all. Where is the way where light dwells? and as for darkness, where is its place, That you should take it to its domain, and that you should know the paths to its home?
We don't know the origin of the sea, death, Earth, or light itself. There is so much that we just don't know. Of each of these uncontrollable forces in the world, only God is in control. It stands to reason that we should let Him handle the rest as well.
