'Living In Darkness' in the Bible

The people living in darkness have seen a great light, and for those living in the land and shadow of death, a light has risen."

If, while we are living in darkness, we profess to have fellowship with Him, we speak falsely and are not adhering to the truth.

But whoever hates his brother is in darkness, and is living in darkness, and he does not know where he is going, for the darkness has blinded his eyes.
