³ We proclaim to you what we have seen and heard,^(A) so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ.^(B)

⁷ But if we walk in the light,^(A) 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.^(B)

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.^(A)

²³ No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.^(A)

²³ And this is his command: to believe^(A) in the name of his Son, Jesus Christ,^(B) and to love one another as he commanded us.^(C)
