2nd Corinthians 10:7

4 for the weapons of our warfare [are] not fleshly, but powerful to God for bringing down of strongholds,

5 reasonings bringing down, and every high thing lifted up against the knowledge of God, and bringing into captivity every thought to the obedience of the Christ,

6 and being in readiness to avenge every disobedience, whenever your obedience may be fulfilled.

7 The things in presence do ye see? if any one hath trusted in himself to be Christ`s, this let him reckon again from himself, that according as he is Christ`s, so also we [are] Christ`s;

8 for even if also anything more abundantly I shall boast concerning our authority, that the Lord gave us for building up, and not for casting you down, I shall not be ashamed;

9 that I may not seem as if I would terrify you through the letters,

10 `because the letters indeed -- saith one -- [are] weighty and strong, and the bodily presence weak, and the speech despicable.`
