How are we supposed to apply the truth that God is light? According to 1 John 1:5–2:1, it means living our lives exposed to God and one another. Being true to ourselves and God about the reality of our sin will produce true fellowship and help us experience true forgiveness. God’s light not only exposes our sin, but in Jesus, purifies us. Therefore, before God, we may be naked but unashamed. We will consider this truth under three broad headings:

1. God’s Exposing Light (1:5)

2. True Fellowship (1:6–7)

3. True Forgiveness (1:8–2:1)
