1 Behold, what manner of love the Father hath
  bestowed upon us, that we should be called the sons
  of God: therefore the world knoweth us not, because
  it knew him not.
   2 Beloved, now are we the sons of God, and it doth
  not yet appear what we shall be: but we know that,
  when he shall appear, we shall be like him; for we
  shall see him as he is.
   3 And every man that hath this hope in him purifieth
  himself, even as he is pure.
   4 Whosoever committeth sin transgresseth also the
  law: for sin is the transgression of the law.
   5 And ye know that he was manifested to take away
  our sins; and in him is no sin.
   6 Whosoever abideth in him sinneth not: whosoever
  sinneth hath not seen him, neither known him.
   7 Little children, let no man deceive you: he that
  doeth righteousness is righteous, even as he is
  righteous.
   8 He that committeth sin is of the devil; for the
  devil sinneth from the beginning. For this purpose
  the Son of God was manifested, that he might destroy
  the works of the devil.
   9 Whosoever is born of God doth not commit sin; for
  his seed remaineth in him: and he cannot sin, because
  he is born 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.
  11 For this is the message that ye heard from the
  beginning, that we should love one another.
  12 Not as Cain, who was of that wicked one, and slew
  his brother. And wherefore slew he him? Because his
  own works were evil, and his brother's righteous.
  13 Marvel not, my brethren, if the world hate you.
  14 We know that we have passed from death unto life,
  because we love the brethren. He that loveth not his
  brother 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 perceive we the love of God, because he
  laid down his life for us: and we ought to lay down
  our lives for the brethren.
  17 But whoso hath this world's good, and seeth his
  brother have need, and shutteth up his bowels of
  compassion from him, how dwelleth the love of God in
  him?
  18 My little children, let us not love in word,
  neither in tongue; but in deed and in truth.
  19 And hereby we know that we are of the truth, and
  shall assure our hearts before him.
  20 For if our heart condemn us, God is greater than
  our heart, and knoweth all things.
  21 Beloved, if our heart condemn us not, then have we
  confidence toward God.
  22 And whatsoever we ask, we receive of him, because
  we keep his commandments, and do those things that
  are pleasing in his sight.
  23 And this is his commandment, That we should
  believe on the name of his Son Jesus Christ, and love
  one another, as he gave us commandment.
  24 And he that keepeth his commandments dwelleth in
  him, and he in him. And hereby we know that he
  abideth in us, by the Spirit which he hath given us.
