John reminds his audience about the life, character, and mission of Jesus- which he witnessed first hand.
Reading a first hand account of an elder who once walked with Jesus during his ministry was a powerful whiteness.
God is light- willing to illuminate and cleanse sinners.
Apart from God, man is darkness- in need to the cleansing light of Christ.
Walk in the light!
This is a good summery of man’s condition and God’s provision. Talk about it often.
God, thank you for being light, but also for inviting me into your light.
