1 Finally, my brethren, rejoice in the Lord. To
  write the same things to you, to me indeed is not
  grievous, but for you it is safe.
   2 Beware of dogs, beware of evil workers, beware of
  the concision.
   3 For we are the circumcision, which worship God in
  the spirit, and rejoice in Christ Jesus, and have no
  confidence in the flesh.
   4 Though I might also have confidence in the flesh.
  If any other man thinketh that he hath whereof he
  might trust in the flesh, I more:
   5 Circumcised the eighth day, of the stock of
  Israel, of the tribe of Benjamin, an Hebrew of the
  Hebrews; as touching the law, a Pharisee;
   6 Concerning zeal, persecuting the church; touching
  the righteousness which is in the law, blameless.
   7 But what things were gain to me, those I counted
  loss for Christ.
   8 Yea doubtless, and I count all things but loss for
  the excellency of the knowledge of Christ Jesus my
  Lord: for whom I have suffered the loss of all
  things, and do count them but dung, that I may win
  Christ,
   9 And be found in him, not having mine own
  righteousness, which is of the law, but that which is
  through the faith of Christ, the righteousness which
  is of God by faith:
  10 That I may know him, and the power of his
  resurrection, and the fellowship of his sufferings,
  being made conformable unto his death;
  11 If by any means I might attain unto the
  resurrection of the dead.
  12 Not as though I had already attained, either were
  already perfect: but I follow after, if that I may
  apprehend that for which also I am apprehended of
  Christ Jesus.
  13 Brethren, I count not myself to have apprehended:
  but this one thing I do, forgetting those things
  which are behind, and reaching forth unto those
  things which are before,
  14 I press toward the mark for the prize of the high
  calling of God in Christ Jesus.
  15 Let us therefore, as many as be perfect, be thus
  minded: and if in any thing ye be otherwise minded,
  God shall reveal even this unto you.
  16 Nevertheless, whereto we have already attained,
  let us walk by the same rule, let us mind the same
  thing.
  17 Brethren, be followers together of me, and mark
  them which walk so as ye have us for an ensample.
  18 (For many walk, of whom I have told you often, and
  now tell you even weeping, that they are the enemies
  of the cross of Christ:
  19 Whose end is destruction, whose God is their
  belly, and whose glory is in their shame, who mind
  earthly things.)
  20 For our conversation is in heaven; from whence
  also we look for the Saviour, the Lord Jesus Christ:
  21 Who shall change our vile body, that it may be
  fashioned like unto his glorious body, according to
  the working whereby he is able even to subdue all
  things unto himself.
