“Bright light! Bright light!”
McFarland sees the Johannine image of God as light to be helpful in explicating the idea of God as present. To say that God is light is not to compare God with created light, for God is light, and, unlike with created light, no darkness is entailed. If anything, the divine light glorifies or highlights the light already visible in the three divine persons through their mutual illumination. But McFarland sees a fitting connection between the notion that God is light, the fact that the first of God’s creatures was light, and the promise that in the new creation, there will be no night but only the unceasing light of God. For McFarland, it seems that the (analogical?) connection between God’s light and created light makes it fitting for God not only to be present to Godself, but also to be present to that which is not God.
