God saw that the light was good; and God separated the light from the darkness (Genesis 1:4, NASB)

Light and darkness – I have so much trouble with those words and their meanings. This seems to imply that the light is good and the darkness is bad. And in some ways that is right because the Light of God is good and I need to walk in His light. But at a more literal level, the darkness is also good because it is in the dark that we find God’s rest and time for our bodies to repair themselves. Perhaps that was not necessary at this point in time, before the fall, but now we, I, need that rest time. So what are you trying to tell me, Abba? Am I to be taking this literally, in this world, or am I to take this in a spiritual sense of evil vs. good? I am thinking that maybe it should be a literal meaning because when this is written, the fall had not yet occurred. In my understanding everything You created was good, so the darkness would be good and necessary for mankind. But on the other hand, it only says that the light was good. So I am confused and need some enlightenment on this. I pray You will give me a greater understanding.
