21 My little children, these things write I unto you that ye may not sin. And if any man sin, we have an Advocate with the Father, Jesus Christ the righteous: 2 and he is the propitiation for our sins; and not for ours only, 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 saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him; 5 but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him: 6 he that saith he abideth in him ought himself also to walk even as he walked.

7 Beloved, no new commandment write I unto you, but an old commandment which ye had from the beginning: the old commandment is the word which ye heard. 8 Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth. 9 He that saith he is in the light and hateth his brother, is in the darkness even until now. 10 He that loveth his brother abideth in the light, and there is no occasion of stumbling in him. 11 But he that hateth his brother is in the darkness, and walketh in the darkness, and knoweth not whither he goeth, because the darkness hath blinded his eyes.

12 I write unto you, [my] little children, because your sins are forgiven you for his name's sake. 13 I write unto you, fathers, because ye know him who is from the beginning. I write unto you, young men, because ye have overcome the evil one. I have written unto you, little children, because ye know the Father. 14 I have written unto you, fathers, because ye know him who is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the evil one. 15 Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him. 16 For all that is in the world, the lust of the flesh and the lust of the eyes and the vain glory of life, is not of the Father, but is of the world. 17 And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.

The Antichrist

18 Little children, it is the last hour: and as ye heard that antichrist cometh, even now have there arisen many antichrists; whereby we know that it is the last hour. 19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us: but [they went out], that they might be made manifest that they all are not of us.

20 And ye have an anointing from the Holy One, and ye know all the things. 21 I have not written unto you because ye know not the truth, but because ye know it, and because no lie is of the truth. 22 Who is the liar but he that denieth that Jesus is the Christ? This is the antichrist, [even] he that denieth the Father and the Son. 23 Whosoever denieth the Son, the same hath not the Father: he that confesseth the Son hath the Father also. 24 As for you, let that abide in you which ye heard from the beginning. If that which ye heard from the beginning abide in you, ye also shall abide in the Son, and in the Father. 25 And this is the promise which he promised us, [even] the life eternal. 26 These things have I written unto you concerning them that would lead you astray. 27 And as for you, the anointing which ye received of him abideth in you, and ye need not that any one teach you; but as his anointing teacheth you; concerning all things, and is true, and is no lie, and even as it taught you, ye abide in him.

The Children of God and Righteousness

28 And now, [my] little children, abide in him; that, if he shall be manifested, we may have boldness, and not be ashamed before him at his coming. 29 If ye know that he is righteous, ye know that every one also that doeth righteousness is begotten of him.

31 Behold what manner of love the Father hath bestowed upon us, that we should be called children of God; and [such] we are. For this cause the world knoweth us not, because it knew him not. 2 Beloved, now are we children of God, and it is not yet made manifest what we shall be. We know that, if he shall be manifested, we shall be like him; for we shall see him even as he is. 3 And every one that hath this hope [set] on him purifieth himself, even as he is pure.

4 Every one that doeth sin doeth also lawlessness; and sin is lawlessness. 5 And ye know that he was manifested to take away sins; and in him is no sin. 6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither knoweth him. 7 [My] little children, let no man lead you astray: he that doeth righteousness is righteous, even as he is righteous: 8 he that doeth sin is of the devil; for the devil sinneth from the beginning. To this end was the Son of God manifested, that he might destroy the works of the devil. 9 Whosoever is begotten of God doeth no sin, because his seed abideth in him: and he cannot sin, because he is begotten of God. 10 In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.

Love One Another

11 For this is the message which ye heard from the beginning, that we should love one another: 12 not as Cain was of the evil one, and slew his brother. And wherefore slew he him? Because his works were evil, and his brother's righteous. 13 Marvel not, brethren, if the world hateth you.

14 We know that we have passed out of death into life, because we love the brethren. He that loveth not abideth in death. 15 Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him. 16 Hereby know we love, because he laid down his life for us: and we ought to lay down our lives for the brethren. 17 But whoso hath the world's goods, and beholdeth his brother in need, and shutteth up his compassion from him, how doth the love of God abide in him? 18 [My] Little children, let us not love in word, neither with the tongue; but in deed and truth. 19 Hereby shall we know that we are of the truth, and shall assure our heart before him:

20 because if our heart condemn us, God is greater than our heart, and knoweth all things. 21 Beloved, if our heart condemn us not, we have boldness toward God; 22 and whatsoever we ask we receive of him, because we keep his commandments and do the things that are pleasing in his sight.

23 And this is his commandment, that we should believe in the name of his Son Jesus Christ, and love one another, even as he gave us commandment. 24 And he that keepeth his commandments abideth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he gave us.
