Scripture to Memorize: 1 John 1:10
If we say we have not sinned, we make him a liar, and his word is not in us.
Day 1 Read: 1 John 1:5
This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.
Reflect: How does John summarize the teachings of Jesus? What definitive statements does he make?
Consider: In describing God as Light, which John frequently did (John 1:4–5, 7–9; 3:19–21; 8:12; 9:5; 12:35–36, 46; Rev. 21:23), he was no doubt thinking of God as the Revealer of His holiness. Both aspects of the divine nature figure in the discussion of sin and fellowship in 1 John 1:6–10. As Light, God both exposes man’s sin and condemns it. If anyone walks in darkness, he is hiding from the truth which the Light reveals. Thus, revelatory terms such as “the truth” and “His Word” are prominent in 1 John 1:6, 8, 10.
Respond: Spend time meditating on the phrase ‘God is light’ and all that entails. Next, list things in this world that are ‘dark’. Nothing you can put in that category is of God. Nothing in that category characterizes God. Worship your God who is Light!
