2 Corinthians 11:13-21

13 For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
14 And no marvel; for Satan himself is transformed into an angel of light.
15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
16 I say again, Let no man think me a fool; if otherwise, yet as a fool receive me, that I may boast myself a little.
17 That which I speak, I speak it not after the Lord, but as it were foolishly, in this confidence of boasting.
18 Seeing that many glory after the flesh, I will glory also.
19 For ye suffer fools gladly, seeing ye yourselves are wise.
20 For ye suffer, if a man bring you into bondage, if a man devour you, if a man take of you, if a man exalt himself, if a man smite you on the face.
21 I speak as concerning reproach, as though we had been weak. Howbeit whereinsoever any is bold, (I speak foolishly,) I am bold also.
