1 John 2:21-23

Young's Literal Translation

²¹ I did not write to you because ye have not known the truth, but because ye have known it, and because no lie is of the truth.

²² Who is the liar, except he who is denying that Jesus is the Christ? this one is the antichrist who is denying the Father and the Son;

²³ every one who is denying the Son, neither hath he the Father, [he who is confessing the Son hath the Father also.]
