20 But you have an anointing from the Holy One, and all of you know the truth.[1] 21 I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. 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. 23 No one who denies the Son has the Father; whoever acknowledges the Son has the Father also. 24 As for you, see that what you have heard from the beginning remains in you. If it does, you also will remain in the Son and in the Father. 25 And this is what he promised us-eternal life. 26 I am writing these things to you about those who are trying to lead you astray.

Commentary on 1 John 2:18-23

(Read 1 John 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.

Commentary on 1 John 2:24-29

(Read 1 John 2:24-29)

The truth of Christ, abiding in us, is a means to sever from sin, and unites us to the Son of God, John 15:3,4. What value should we put upon gospel truth! Thereby the promise of eternal life is made sure. The promise God makes, is suitable to his own greatness, power, and goodness; it is eternal life. The Spirit of truth will not lie; and he teaches all things in the present dispensation, all things necessary to our knowledge of God in Christ, and their glory in the gospel. The apostle repeats the kind words, "little children;" which denotes his affection. He would persuade by love. Gospel privileges oblige to gospel duties; and those anointed by the Lord Jesus abide with him. The new spiritual nature is from the Lord Christ. He that is constant to the practice of religion in trying times, shows that he is born from above, from the Lord Christ. Then, let us beware of holding the truth in unrighteousness, remembering that those only are born of God, who bear his holy image, and walk in his most righteous ways.
