Also, in the opening verses of the Gospel of John, Jesus is described as the light which the darkness cannot overcome. Here in 1 John is the simple presentation of that thought more fully -- God is perfect light. The implication that follows is that when a person does or says something that has a dark component, it is the opposite of God and thus sinful. Faithful Christians, who are awaiting eternal life, strive always to walk in the light of God.
