The verse in its chapter

1 John 1:5-9

  1. 5 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.
  2. 6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
  3. 7 But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
  4. 8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
  5. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.

Study note

Tyndale Open Study Notes (CC BY-SA 4.0).

1:7 Believers have fellowship with each other and with God as they live in the light. People cannot say they commune with God and then refuse to have fellowship with God’s people. This was the case with the Gnostics. The apostles of Christ had known Jesus Christ as God-in-the-flesh and were continuing to have spiritual fellowship with him (1:3).
