1 My little children, these things write I unto you,
  that ye sin not. 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 sins of the whole
  world.
   3 And hereby we do 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 is the
  love of God perfected: hereby know we that we are in
  him.
   6 He that saith he abideth in him ought himself also
  so to walk, even as he walked.
   7 Brethren, I write no new commandment unto you, but
  an old commandment which ye had from the beginning.
  The old commandment is the word which ye have heard
  from the beginning.
   8 Again, a new commandment I write unto you, which
  thing is true in him and in you: because the darkness
  is past, and the true light now shineth.
   9 He that saith he is in the light, and hateth his
  brother, is in darkness even until now.
  10 He that loveth his brother abideth in the light,
  and there is none occasion of stumbling in him.
  11 But he that hateth his brother is in darkness, and
  walketh in darkness, and knoweth not whither he
  goeth, because that darkness hath blinded his eyes.
  12 I write unto you, little children, because your
  sins are forgiven you for his name's sake.
  13 I write unto you, fathers, because ye have known
  him that is from the beginning. I write unto you,
  young men, because ye have overcome the wicked one. I
  write unto you, little children, because ye have
  known the Father.
  14 I have written unto you, fathers, because ye have
  known him that 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
  wicked 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 pride 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.
  18 Little children, it is the last time: and as ye
  have heard that antichrist shall come, even now are
  there many antichrists; whereby we know that it is
  the last time.
  19 They went out from us, but they were not of us;
  for if they had been of us, they would no doubt have
  continued with us: but they went out, that they might
  be made manifest that they were not all of us.
  20 But ye have an unction from the Holy One, and ye
  know all things.
  21 I have not written unto you because ye know not
  the truth, but because ye know it, and that no lie is
  of the truth.
  22 Who is a liar but he that denieth that Jesus is
  the Christ? He is antichrist, that denieth the Father
  and the Son.
  23 Whosoever denieth the Son, the same hath not the
  Father: (but) he that acknowledgeth the Son hath the
  Father also.
  24 Let that therefore abide in you, which ye have
  heard from the beginning. If that which ye have heard
  from the beginning shall remain in you, ye also shall
  continue in the Son, and in the Father.
  25 And this is the promise that he hath promised us,
  even eternal life.
  26 These things have I written unto you concerning
  them that seduce you.
  27 But the anointing which ye have received of him
  abideth in you, and ye need not that any man teach
  you: but as the same anointing teacheth you of all
  things, and is truth, and is no lie, and even as it
  hath taught you, ye shall abide in him.
  28 And now, little children, abide in him; that, when
  he shall appear, we may have confidence, and not be
  ashamed before him at his coming.
  29 If ye know that he is righteous, ye know that
  every one that doeth righteousness is born of him.
