An interesting question was raised in the comments of this post about the identity of good and evil. My response:
I find the metaphor of light and darkness very helpful here. “God is light, and in Him is no darkness at all.” (1 John 1:5) Dichotomy and congealment both imply a form of equality between good and evil, which I reject. There is only really Good and otherwise, light or darkness. Evil, absurdity, they are only temporal, and will be done away with. There is no dichotomy, Good overpowers evil as easily as light overpowers darkness. There is no congealment. Light and darkness can not coexist. Good and evil are completely mutually exclusive.
This is not to say that Good may not display characteristics which WE THINK are Evil. God (the very definition of Good) has (at various times according to the Bible) condoned genocide, lying, gender inequality, pillaging, military conquest, sexual slavery, carousing, violence, and human sacrifice. I’m not saying that we’ll always like the Good. I’m just saying that, fundamentally, Good and Evil can’t mix. When you mix light with darkness, all you get is light. God abides no rivals.
“Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.” (1 Thess 5:5)
“And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.” (John 3:19)
“And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.” (Rev 22:5)
