18 Dear children, the last hour is here. You have heard that the Antichrist is coming, and already many such antichrists have appeared. From this we know that the last hour has come. 19 These people left our churches, but they never really belonged with us; otherwise they would have stayed with us. When they left, it proved that they did not belong with us.
20 But you are not like that, for the Holy One has given you his Spirit, and all of you know the truth. 21 So I am writing to you not because you don't know the truth but because you know the difference between truth and lies. 22 And who is a liar? Anyone who says that Jesus is not the Christ. Anyone who denies the Father and the Son is an antichrist. 23 Anyone who denies the Son doesn't have the Father, either. But anyone who acknowledges the Son has the Father also. 24 So you must remain faithful to what you have been taught from the beginning. If you do, you will remain in fellowship with the Son and with the Father. 25 And in this fellowship we enjoy the eternal life he promised us. 26 I am writing these things to warn you about those who want to lead you astray. 27 But you have received the Holy Spirit, and he lives within you, so you don't need anyone to teach you what is true. For the Spirit teaches you everything you need to know, and what he teaches is true-it is not a lie. So just as he has taught you, remain in fellowship with Christ.
28 And now, dear children, remain in fellowship with Christ so that when he returns, you will be full of courage and not shrink back from him in shame. 29 Since we know that Christ is righteous, we also know that all who do what is right are God's children.

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.
