15 Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.
2 Corinthians 11:13-16:
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.
