1 John 2.11 reads: "Whoever hates his brother is in darkness; he walks in darkness and does not know where he is going because the darkness blinded his eyes." What's interesting is that John said that the darkness "blinded" the eyes. I thought about it and saw that he's right. Since God is light, when we have God, we see clearly what is good and what is evil ~ so the light of God is not blinding at all; in fact, it lights our way. As for the one who walks in darkness, he doesn't see good from evil and is therefore like a blind person. When you don't see the light of God, you are indeed blind.
