“And God saw the light, that it was good: and God divided the light from the darkness.”
When God saw the light was good, He separated it from the darkness.
In Matthew 5:4, Jesus says that we are the "light of the world." If we are the "light of the world", and God sees that the light is good, then it stands to reason that He would choose to separate us from the darkness. God created us, then called us to be His children.
1 Thessalonians 5:5 says that we are all children of the light. If we are in the dark, it is because WE choose to be so.
“And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.”
God will not do for us what we do not wish Him to do for us.
If you are in a dark place in your life, then ask that God intervene. Until you do, He, being a just and loving God, will give you what you obviously want.
