1My children, I am writing this to prevent you from sinning; but if anyone does sin, we have an advocatewith the Father, Jesus Christ, the upright. 2He is the sacrifice to expiate our sins, and not only ours, but also those of the whole world. 3In this way we know that we have come to know him, if we keep his commandments. 4Whoever says, 'I know him' without keeping his commandments, is a liar, and truth has no place in him. 5But anyone who does keep his word, in such a one God's love truly reaches its perfection. This is theproof that we are in God. 6Whoever claims to remain in him must act as he acted. 7My dear friends, this is not a new commandment I am writing for you, but an old commandment that youhave had from the beginning; the old commandment is the message you have heard. 8Yet in another way, I am writing a new commandment for you -- and this is true for you, just as much asfor him -- for darkness is passing away and the true light is already shining. 9Whoever claims to be in light but hates his brother is still in darkness. 10Anyone who loves his brother remains in light and there is in him nothing to make him fall away. 11But whoever hates his brother is in darkness and is walking about in darkness not knowing where he isgoing, because darkness has blinded him. 12I am writing to you, children, because your sins have been forgiven through his name. 13I am writing to you, fathers, because you have come to know the One who has existed since thebeginning. I am writing to you, young people, because you have overcome the Evil One. 14I have written to you, children, because you have come to know the Father. I have written to you,parents, because you have come to know the One who has existed since the beginning. I have written to you,young people, because you are strong, and God's word remains in you, and you have overcome the Evil One. 15Do not love the world or what is in the world. If anyone does love the world, the love of the Father findsno place in him, 16because everything there is in the world -- disordered bodily desires, disordered desires of the eyes,pride in possession -- is not from the Father but is from the world. 17And the world, with al its disordered desires, is passing away. But whoever does the will of Godremains for ever. 18Children, this is the final hour; you have heard that the Antichrist is coming, and now many Antichristshave already come; from this we know that it is the final hour. 19They have gone from among us, but they never real y belonged to us; if they had belonged to us, theywould have stayed with us. But this was to prove that not one of them belonged to us. 20But you have been anointed by the Holy One, and have al received knowledge. 21I have written to you not because you are ignorant of the truth, but because you are wel aware of it,and because no lie can come from the truth. 22Who is the liar, if not one who claims that Jesus is not the Christ? This is the Antichrist, who deniesboth the Father and the Son. 23Whoever denies the Son cannot have the Father either; whoever acknowledges the Son has theFather too. 24Let what you heard in the beginning remain in you; as long as what you heard in the beginningremains in you, you will remain in the Son and in the Father. 25And the promise he made you himself is eternal life. 26So much have I written to you about those who are trying to lead you astray. 27But as for you, the anointing you received from him remains in you, and you do not need anyone toteach you; since the anointing he gave you teaches you everything, and since it is true, not false, remain in himjust as he has taught you. 28Therefore remain in him now, children, so that when he appears we may be fearless, and not shrinkfrom him in shame at his coming. 29If you know that he is upright you must recognise that everyone whose life is upright is a child of his.
