[one Lord one faith one baptism]

1 John 2:22-23

who is the liar but he who denies Jesus is the Christ? this is the antichrist, he who denies the Father and the Son. NO ONE WHO DENIES THE SON HAS THE FATHER. He who confesses the Son has the Father also.

so John 8 would appear to apply to anyone, just not those particular Jews being addressed.

[af_vet_1981]

1. When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee? She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more.
2. Master, what shall I do to inherit eternal life? 26He said unto him, What is written in the law? how readest thou? 27And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. 28And he said unto him, Thou hast answered right: this do, and thou shalt live.
3. And hereby we do know that we know him, if we keep his commandments. He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him. But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him. He that saith he abideth in him ought himself also so to walk, even as he walked.
