21 My children, these things I write to you in order that ye may not sin; and if any one sin, we have a patron with the Father, Jesus Christ [the] righteous; 2 and he is the propitiation for our sins; but not for ours alone, but also for the whole world.

Tests of True Knowledge

3 And hereby we know that we know him, if we keep his commandments. 4 He that says, I know him, and does not keep his commandments, is a liar, and the truth is not in him; 5 but whoever keeps his word, in him verily the love of God is perfected. Hereby we know that we are in him. 6 He that says he abides in him ought, even as he walked, himself also [so] to walk.

7 Beloved, I write no new commandment to you, but an old commandment, which ye have had from the beginning. The old commandment is the word which ye heard. 8 Again, I write a new commandment to you, which thing is true in him and in you, because the darkness is passing and the true light already shines. 9 He who says he is in the light, and hates his brother, is in the darkness until now. 10 He that loves his brother abides in light, and there is no occasion of stumbling in him. 11 But he that hates his brother is in the darkness, and walks in the darkness, and knows not where he goes, because the darkness has blinded his eyes.

12 I write to you, children, because [your] sins are forgiven you for his name's sake. 13 I write to you, fathers, because ye have known him [that is] from the beginning. I write to you, young men, because ye have overcome the wicked [one]. I write to you, little children, because ye have known the Father. 14 I have written to you, fathers, because ye have known him [that is] from the beginning. I have written to you, young men, because ye are strong, and the word of God abides in you, and ye have overcome the wicked [one]. 15 Love not the world, nor the things in the world. If any one love the world, the love of the Father is not in him; 16 because all that [is] in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. 17 And the world is passing, and its lust, but he that does the will of God abides for eternity.

The Antichrist

18 Little children, it is [the] last hour, and, according as ye have heard that antichrist comes, even now there have come many antichrists, whence we know that it is [the] last hour. 19 They went out from among us, but they were not of us; for if they had been of us, they would have surely remained with us, but that they might be made manifest that none are of us.

20 And ye have [the] unction from the holy [one], and ye know all things. 21 I have not written to you because ye do not know the truth, but because ye know it, and that no lie is of the truth. 22 Who is the liar but he who denies that Jesus is the Christ? He is the antichrist who denies the Father and the Son. 23 Whoever denies the Son has not the Father either; he who confesses the Son has the Father also. 24 As for you let that which ye have heard from the beginning abide in you: if what ye have heard from the beginning abides in you, ye also shall abide in the Son and in the Father. 25 And this is the promise which he has promised us, life eternal. 26 These things have I written to you concerning those who lead you astray: 27 and yourselves, the unction which ye have received from him abides in you, and ye have not need that any one should teach you; but as the same unction teaches you as to all things, and is true and is not a lie, and even as it has taught you, ye shall abide in him.

The Children of God and Righteousness

28 And now, children, abide in him, that if he be manifested we may have boldness, and not be put to shame from before him at his coming. 29 If ye know that he is righteous, know that every one who practises righteousness is begotten of him.

31 See what love the Father has given to us, that we should be called [the] children of God. For this reason the world knows us not, because it knew him not. 2 Beloved, now are we children of God, and what we shall be has not yet been manifested; we know that if it is manifested we shall be like him, for we shall see him as he is. 3 And every one that has this hope in him purifies himself, even as he is pure.

4 Every one that practises sin practises also lawlessness; and sin is lawlessness. 5 And ye know that he has been manifested that he might take away our sins; and in him sin is not. 6 Whoever abides in him, does not sin: whoever sins, has not seen him or known him. 7 Children, let no man lead you astray; he that practises righteousness is righteous, even as he is righteous. 8 He that practises sin is of the devil; for from [the] beginning the devil sins. To this end the Son of God has been manifested, that he might undo the works of the devil. 9 Whoever has been begotten of God does not practise sin, because his seed abides in him, and he cannot sin, because he has been begotten of God. 10 In this are manifest the children of God and the children of the devil. Whoever does not practise righteousness is not of God, and he who does not love his brother.

Love One Another

11 For this is the message which ye have heard from the beginning, that we should love one another: 12 not as Cain was of the wicked one, and slew his brother; and on account of what slew he him? because his works were wicked, and those of his brother righteous. 13 Do not wonder, brethren, if the world hate you.

14 We know that we have passed from death to life, because we love the brethren. He who does not love [his] brother abides in death. 15 Every one that hates his brother is a murderer, and ye know that no murderer has eternal life abiding in him. 16 Hereby we have known love, because he has laid down his life for us; and we ought for the brethren to lay down [our] lives. 17 But whoso may have the world's substance, and see his brother having need, and shut up his bowels from him, how abides the love of God in him? 18 Children, let us not love with word, nor with tongue, but in deed and in truth. 19 And hereby we shall know that we are of the truth, and shall persuade our hearts before him—

20 that if our heart condemn us, God is greater than our heart and knows all things. 21 Beloved, if our heart condemn us not, we have boldness towards God, 22 and whatsoever we ask we receive from him, because we keep his commandments, and practise the things which are pleasing in his sight.

23 And this is his commandment, that we believe on the name of his Son Jesus Christ, and that we love one another, even as he has given us commandment. 24 And he that keeps his commandments abides in him, and he in him. And hereby we know that he abides in us, by the Spirit which he has given to us.
