2 Corinthians 11:12-14

11:12 And what I am doing I will continue to do, so that I may eliminate any opportunity for those who want a chance to be regarded as our equals in the things they boast about. 11:13 For such people are false apostles, deceitful workers, disguising themselves as apostles of Christ. 11:14 And no wonder, for even Satan disguises himself as an angel of light.
