1 My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One. 2 He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
3 Love and Hatred for Fellow Believers
3 We know that we have come to know him if we keep his commands. 4 Those who say, "I know him," but do not do what he commands are liars, and the truth is not in them. 5 But if anyone obeys his word, love for God[a] is truly made complete in them. This is how we know we are in him: 6 Whoever claims to live in him must live as Jesus did.
7 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard. 8 Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining.
9 Those who claim to be in the light but hate a fellow believer are still in the darkness. 10 Those who love their fellow believers live in the light, and there is nothing in them to make them stumble. 11 But those who hate a fellow believer are in the darkness and walk around in the darkness; they do not know where they are going, because the darkness has blinded them.
12 Reasons for Writing
14 I write to you, dear children, 14 because you know the Father. 14 I write to you, fathers, 14 because you know him who is from the beginning. 14 I write to you, young people, 14 because you are strong, 14 and the word of God lives in you, 14 and you have overcome the evil one.
15 On Not Loving the World
15 Do not love the world or anything in the world. If you love the world, love for the Father[b] is not in you. 16 For everything in the world—the cravings of sinful people, the lust of their eyes and their boasting about what they have and do—comes not from the Father but from the world. 17 The world and its desires pass away, but whoever does the will of God lives forever.
18 Warnings Against Denying the Son
18 Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour. 19 They went out from us, but they did not really belong to us. For if they had belonged to us, they would have remained with us; but their going showed that none of them belonged to us.
20 But you have an anointing from the Holy One, and all of you know the truth.[c] 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 Messiah.[d] 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.
26 I am writing these things to you about those who are trying to lead you astray. 27 As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.
28 God's Children and Sin
28 And now, dear children, continue in him, so that when he appears we may be confident and unashamed before him at his coming.
29 If you know that he is righteous, you know that everyone who does what is right has been born of him.
