"This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all."
— 1 John 1:5 (World English Bible)
Surrounding context
(and the life was revealed, and we have seen, and testify, and declare to you the life, the eternal life, which was with the Father, and was revealed to us);
that which we have seen and heard we declare to you, that you also may have fellowship with us. Yes, and our fellowship is with the Father, and with his Son, Jesus Christ.
And we write these things to you, that our joy may be fulfilled.
This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all.
If we say that we have fellowship with him and walk in the darkness, we lie, and don’t tell the truth.
But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus Christ, his Son, cleanses us from all sin.
If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Explanation
1 John 1:5 opens with John declaring a foundational truth he received directly from Jesus Christ and now passes on to his readers: God is light, and there is no darkness in him whatsoever. In plain language, this means God is entirely pure, truthful, holy, and morally perfect. There is no mixture of evil, deceit, or corruption in his character—none at all. The phrase "no darkness at all" is emphatic in the Greek, leaving absolutely no room for exceptions. God's nature is wholly consistent: what he reveals of himself is trustworthy because there is nothing hidden, false, or corrupt behind it.
The apostle John wrote this letter likely toward the end of the first century to Christian communities facing internal threats from false teachers, often associated with early Gnostic ideas. These teachers claimed special spiritual knowledge while downplaying the seriousness of sin, sometimes even claiming to have fellowship with God while living in ways that contradicted his character. John writes to reassure genuine believers of the truth they had already heard from the apostles—teaching that traces back to Jesus himself—and to expose the inconsistency of anyone claiming intimacy with God while walking in moral darkness. This verse serves as the theological anchor for the rest of the chapter, where John contrasts walking in light with walking in darkness.
Theologically, this verse establishes God's holiness as an absolute, unchanging reality rather than a matter of degree. Light in Scripture often symbolizes truth, purity, and revelation, while darkness symbol
