In this respect a comparison may be made with the heat and light from the sun of this world, which causes vegetation in trees and shrubs even when they are out of its direct rays and under a clouded sky, provided the sun has risen and shown itself in the world. It is the same with the light and heat of heaven from the Lord as the sun, this light being Divine truth, the source of all intelligence and wisdom to angels and men. It is therefore said of the Word:
That it was with God, and was God; that it enlightens every man that comes into the world (John 1:1, 9); and also that that light appears in the darkness (John 1:5).
