Passage
If we say that we have fellowship with him and walk in the darkness, we lie, and do not the truth:
If we say that we have fellowship with him and walk in the darkness, we lie, and do not the truth:
1 John 1:4 and these things we write, that our joy may be made full.
1 John 1:5 And this is the message which we have heard from him and announce unto you, that God is light, and in him is no darkness at all.
1 John 1:6 If we say that we have fellowship with him and walk in the darkness, we lie, and do not the truth:
1 John 1:7 but if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus his Son cleanseth us from all sin.
1 John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
The verse centers on "darkness", "fellowship", "walk", and "truth". It is saying that the verse draws attention to "darkness" and "fellowship", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 5's "And this is the message which we..." into verse 7's "but if we walk in the light...", so "darkness" and "fellowship" belong inside that flow. In 1 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "darkness" and "fellowship" with trust shaped by these words, not by a vague optimism outside the passage.
