Let no one deceive you with empty words, for because of such things the wrath of God is coming on the sons of disobedience. Ephesians 5:6

“Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves. You can identify them by their fruit, that is, by the way they act. They will be known by their actions, whether their conduct is pure and upright.”
