In the sense that sinful men require grace, man can be said to be in the dark, and darkness is understood to be the grace of God which covers his sin. We should come to the light.

Light represents God's Holiness. Holiness is expressed through law, judgment, condemnation, and separation. God's nature did not change when he said “Let there be Light” for the attributes of Holiness were hidden in His name, Elohim. The childish pun 'a lo khoom' means 'not dark'. The light was made manifest as soon as there was something created to be separate from.

The star on the top of the tree is the great light of holiness which came into the world. It is the first light at the dawn of creation, the light that guided shepherds and kings to his birth and shown forth from the tomb. This light reminds us that God is Holy. There is none like him.

God reveals himself two ways. The Holy Ghost represents the message that God is Holy, even though he is also later seen to be another Comforter. The Son represents the message that God is Love, though he lived the Holy life. God's representation of Himself as Holiness and Love is reconciled on the cross where the judgment of man is satisfied by the death of Christ, and his love extended by his forgiveness of us.
