1 Now I Paul myself beseech you by the
       meekness and gentleness of Christ, who in
       presence am base among you, but being absent am
       bold toward you:
        2 But I beseech you, that I may not be bold
       when I am present with that confidence,
       wherewith I think to be bold against some, which
       think of us as if we walked according to the
       flesh.
        3 For though we walk in the flesh, we do not
       war after the flesh:
        4 (For the weapons of our warfare are not
       carnal, but mighty through God to the pulling
       down of strong holds;)
        5 Casting down imaginations, and every high
       thing that exalteth itself against the knowledge
       of God, and bringing into captivity every
       thought to the obedience of Christ;
        6 And having in a readiness to revenge all
       disobedience, when your obedience is fulfilled.
        7 Do ye look on things after the outward
       appearance? If any man trust to himself that he
       is Christ's, let him of himself think this
       again, that, as he is Christ's, even so are we
       Christ's.
        8 For though I should boast somewhat more of
       our authority, which the Lord hath given us for
       edification, and not for your destruction, I
       should not be ashamed:
        9 That I may not seem as if I would terrify you
       by letters.
       10 For his letters, say they, are weighty and
       powerful; but his bodily presence is weak, and
       his speech contemptible.
       11 Let such an one think this, that, such as we
       are in word by letters when we are absent, such
       will we be also in deed when we are present.
       12 For we dare not make ourselves of the number,
       or compare ourselves with some that commend
       themselves: but they measuring themselves by
       themselves, and comparing themselves among
       themselves, are not wise.
       13 But we will not boast of things without our
       measure, but according to the measure of the
       rule which God hath distributed to us, a measure
       to reach even unto you.
       14 For we stretch not ourselves beyond our
       measure, as though we reached not unto you: for
       we are come as far as to you also in preaching
       the gospel of Christ:
       15 Not boasting of things without our measure,
       that is, of other men's labours; but having
       hope, when your faith is increased, that we
       shall be enlarged by you according to our rule
       abundantly,
       16 To preach the gospel in the regions beyond
       you, and not to boast in another man's line of
       things made ready to our hand.
       17 But he that glorieth, let him glory in the
       Lord.
       18 For not he that commendeth himself is
       approved, but whom the Lord commendeth.
