The Light trumps all

I John 1:5 And this is the message we have heard from Him and announce to you, that God is light, and in Him there is no darkness at all.(NAS)

There are many ways in which the metaphor of God being light can be taken, but the most recent idea that I have found in this verse is this: when you shine a flashlight on a shadow, the light overwhelms the darkness, not the other way around. God, in His holiness, is infinitely more powerful than anything evil. In many religious beliefs and cultures, the common belief is held that good and evil are equal, or that Satan is the opposite of God. God has no equal opposite. There is nothing that stands up when compared to God's holiness. The darkness melts in the presence of the light. End of story.
