⁶ If we claim to have fellowship with him and yet walk in the darkness,^(A) we lie and do not live out the truth.^{(B) 7} But if we walk in the light,^(C) 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.^(D)

Love and Hatred for Fellow Believers

³ We know^(A) that we have come to know him^(B) if we keep his commands.^{(C) 4} Whoever says, “I know him,”^(D) but does not do what he commands is a liar, and the truth is not in that person.^{(E) 5} But if anyone obeys his word,^(F) love for God^[a] is truly made complete in them.^(G) This is how we know^(H) we are in him: ⁶ Whoever claims to live in him must live as Jesus did.^(I)

²¹ Dear friends,^(A) if our hearts do not condemn us, we have confidence before God^{(B) 22} and receive from him anything we ask,^(C) because we keep his commands^(D) and do what pleases him.^{(E) 23} And this is his command: to believe^(F) in the name of his Son, Jesus Christ,^(G) and to love one another as he commanded us.^{(H) 24} The one who keeps God’s commands^(I) lives in him,^(J) and he in them. And this is how we know that he lives in us: We know it by the Spirit he gave us.^(K)
