Why was the lamb slain at the foundation of the world? So that light could become darkness, good could become evil, the sinless could become sin, and we could have sentient life with free will.
The Lamb of God
The Father of Lights
The phrase "the father of lights," is sweet and poetic. It's spiritually accurate in identifying two roles of God the Father. It's also accurate physics.
Marvellous Light
Jesus is the light. If you're a Christian you're the light. Others hate the light.
Everlasting Light
We're told that the new heaven and new Earth, where we'll life for eternity, is a place of perpetual light. We're making the case that this permanent physical separation of light from darkness is the purpose of creation.
The Light of Life
Things on Earth are patterned after things in the heavens. God has withdrawn his presence from the world and dwells in a realm of light, while we are here on Earth toiling through an ever encroaching darkness.

Christ became sin for us by sacrificially allowing protons to emit their light and become neutrons during nucleosynthesis. "The lamb slain from the foundation of the world," isn't poetic or symbolic, it's physics.
