This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. John presents the foundational revelation received from Christ: God is light. This is not metaphor but essential nature—light defines God's very being. In Scripture, light represents holiness, truth, purity, knowledge, and life. "In him is no darkness at all" eliminates any dualism: there is no mixture, shadow, or variation in God's moral perfection. The emphatic double negative (skotia en autō ouk estin oudemia, σκοτία ἐν αὐτῷ οὐκ ἔστιν οὐδεμία) removes all possibility of moral compromise in God.
The source is crucial: this message was "heard of him"—from Christ Himself. It's not human speculation about God's nature but divine self-revelation. "Declare" (anangellomen, ἀναγγέλλομεν) means to announce authoritatively, like a herald proclaiming royal decree.
This truth has profound implications for fellowship with God and full joy. If God is absolute light, fellowship with Him requires walking in light. There can be no compromise with darkness—no secret sins, cherished lies, or moral relativism. The exclusiveness of light and darkness establishes Christianity's exclusive claims: light cannot fellowship with darkness.
Historical Context
The declaration "God is light" directly challenged both pagan and Gnostic theology. Greek philosophy sometimes associated the divine with light, but typically as one attribute among others. Gnosticism taught dualism—light and darkness as equal, eternal principles. Some Gnostic systems claimed the creator God was evil or ignorant (associated with darkness), while the supreme God was pure light but distant from creation.
John's absolute statement refutes these errors. The God who created the material world is pure light with no mixture of darkness. Creation is not a cosmic mistake or the work of an inferior deity. Against moral relativism in Greco-Roman culture, John declares absolute moral standards rooted in God's unchanging character.
The Old Testament background includes passages like Psalm 27:1, Isaiah 60:19, and James 1:17. John presents Jesus as the fulfillment of this light-imagery—"the true Light" (John 1:9), "the light of the world" (John 8:12).
