2 Corinthians 11:10-15

As the truth of Christ is in me, no man shall stop me of this boasting in the regions of Achaia. Wherefore? because I love you not? God knoweth. But what I do, that I will do, that I may cut off occasion from them which desire occasion; that wherein they glory, they may be found even as we. For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ. And no marvel; for Satan himself is transformed into an angel of light. 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.
