Light and Darkness, Sin and Forgiveness

⁵ This is the message we have heard^(A) from him and declare to you: God is light;^(B) in him there is no darkness at all. ⁶ If we claim to have fellowship with him and yet walk in the darkness,^(C) we lie and do not live out the truth.^{(D) 7} But if we walk in the light,^(E) as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all^[a] sin.^(F)

⁸ If we claim to be without sin,^(G) we deceive ourselves and the truth is not in us.^{(H) 9} If we confess our sins, he is faithful and just and will forgive us our sins^(I) and purify us from all unrighteousness.^{(J) 10} If we claim we have not sinned,^(K) we make him out to be a liar^(L) and his word is not in us.^(M)

2 My dear children,^(N) I write this to you so that you will not sin. But if anybody does sin, we have an advocate^(O) with the Father—Jesus Christ, the Righteous One. ² He is the atoning sacrifice for our sins,^(P) and not only for ours but also for the sins of the whole world.^(Q)

Love and Hatred for Fellow Believers

³ We know^(R) that we have come to know him^(S) if we keep his commands.^{(T) 4} Whoever says, “I know him,”^(U) but does not do what he commands is a liar, and the truth is not in that person.^{(V) 5} But if anyone obeys his word,^(W) love for God^[b] is truly made complete in them.^(X) This is how we know^(Y) we are in him: ⁶ Whoever claims to live in him must live as Jesus did.^(Z)

Warnings Against Denying the Son

¹⁸ Dear children, this is the last hour;^(A) and as you have heard that the antichrist is coming,^(B) even now many antichrists have come.^(C) This is how we know it is the last hour. ¹⁹ They went out from us,^(D) but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us.^(E)

²⁰ But you have an anointing^(F) from the Holy One,^(G) and all of you know the truth.^{[a](H) 21} I do not write to you because you do not know the truth, but because you do know it^(I) and because no lie comes from the truth. ²² Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son.^{(J) 23} No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.^(K)

²⁴ As for you, see that what you have heard from the beginning^(L) remains in you. If it does, you also will remain in the Son and in the Father.^{(M) 25} And this is what he promised us—eternal life.^(N)

²⁶ I am writing these things to you about those who are trying to lead you astray.^{(O) 27} As for you, the anointing^(P) you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things^(Q) and as that anointing is real, not counterfeit—just as it has taught you, remain in him.^(R)
