2:21 {22} I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.
(22) The taking away of an objection, He did not write these things to men who are ignorant of religion, but rather to those who know the truth well, yes so far that they are able to discern truth from falsehood.
2:21 I have not written unto you, etc. John writes to them as those who know the truth, and know how to discern between the truth and lies.
2:21 I have written - Namely, 1Jo 2:13. To you because ye know the truth - That is, to confirm you in the knowledge ye have already. Ye know that no lie is of the truth - That all the doctrines of these antichrists are irreconcilable to it.
2:18-23 Every man is an antichrist, who denies the Person, or any of the offices of Christ; and in denying the Son, he denies the Father also, and has no part in his favour while he rejects his great salvation. Let this prophecy that seducers would rise in the Christian world, keep us from being seduced. The church knows not well who are its true members, and who are not, but thus true Christians were proved, and rendered more watchful and humble. True Christians are anointed ones; their names expresses this: they are anointed with grace, with gifts and spiritual privileges, by the Holy Spirit of grace. The great and most hurtful lies that the father of lies spreads in the world, usually are falsehoods and errors relating to the person of Christ. The unction from the Holy One, alone can keep us from delusions. While we judge favourably of all who trust in Christ as the Divine Saviour, and obey his word, and seek to live in union with them, let us pity and pray for those who deny the Godhead of Christ, or his atonement, and the new-creating work of the Holy Ghost. Let us protest against such antichristian doctrine, and keep from them as much as we may.
