1 John · chapter 1 of 5
Updated on
1 John 1 opens the letter with the testimony of those who heard, saw and touched the Word of life, Jesus Christ, so that their readers may have fellowship with them and with the Father and the Son. John declares that God is light and that whoever claims fellowship with him must walk in the light; the blood of Jesus cleanses from all sin. Anyone who denies having sin deceives himself, but if we confess our sins, God is faithful and just to forgive.
First John does not begin with a greeting but with an affirmation about the person of Christ. Tradition holds that the apostle John wrote it in old age to strengthen churches shaken by teachers who denied the true humanity of Jesus and the seriousness of sin. This first chapter lays the foundations: the reality of Jesus, fellowship with God and honesty about sin.
John opens the letter with what was from the beginning, what they have heard, seen with their eyes, looked upon and touched with their hands concerning the Word of life. That life was made manifest, and they saw it, testify to it and proclaim it: the eternal life that was with the Father and appeared to them. They proclaim what they have seen and heard so that their readers may have fellowship with them, and that fellowship is with the Father and with his Son Jesus Christ. They write these things so that the joy of all may be complete (vv. 1-4).
The message they have heard from Jesus and proclaim is that God is light, and in him is no darkness at all. If we say we have fellowship with him while we walk in darkness, we lie and do not practice 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 his Son cleanses us from all sin (vv. 5-7).
If we say we have no sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and cleanse us from all unrighteousness. And if we say we have not sinned, we make him a liar and his word is not in us (vv. 8-10).

1 John 1 invites honesty. Walking in the light does not mean never failing but ceasing to hide sin and bringing it to God. In a small group, a setting where people can confess with humility and receive encouragement helps fellowship be real.
The chapter also reminds us that our faith rests on a concrete testimony: Jesus was seen and touched. We can thank God for the witnesses who passed on the gospel and ask whom we are sharing it with.
1 John 1 establishes that the gospel is a real testimony, that God is light and that forgiveness is available to the one who confesses. Chapter 2 continues with obedience, Christ as advocate and the call not to love the world.
The letter does not name its author, but Christian tradition from early on attributes it to the apostle John, who also wrote the Gospel of John. Its style, vocabulary and themes, such as light, life, love and truth, are very similar to those of the fourth Gospel.
No. John writes so that they may not sin (2:1) and says that whoever abides in Christ does not live in sin as a practice. Confession is not a license but the honest response of a believer who fails and returns to God, trusting that Christ is his advocate.
