2 Corinthians 11:4

11:4 For if someone comes and proclaims another Jesus different from the one we proclaimed, or if you receive a different spirit than the one you received, or a different gospel than the one you accepted, you put up with it well enough!

2 Corinthians 11:12-15

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. 11:15 Therefore it is not surprising his servants also disguise themselves as servants of righteousness, whose end will correspond to their actions.
