This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all.

 (iv) The darkness stands for the chaos of life without God. God, says Paul, thinking of the first act of creation, commanded his light to shine out of the darkness ( 2 Corinthians 4:6). Without God's light the world is a chaos, in which life has neither order nor sense.
