2 Corinthians 11:12-15

12But what I do, I will also do, that I may cut off the opportunity of those wishing [for] an opportunity, that wherein they boast they may be found even as we.

13For such [are] false apostles, deceitful workers, transforming themselves into apostles of Christ.

14And [it is] not wonderful, for Satan himself transforms himself into an angel of light.

15It is no great thing therefore if his ministers also transform themselves as ministers of righteousness; whose end shall be according to their works.
