“Beware of Antinomian [that is, being under no obligation to obey the moral and ethical requirements of the Bible—license] books; particularly the works of Dr. Crisp and Mr. Saltmarsh. They contain many excellent things; and this makes them the more dangerous. O be warned in time! Do not play with fire.”
John Wesley, from A Plain Account of Christian Perfection (emphasis added)
I stumbled upon this quote this evening from John Wesley, and was struck by its profundity.
The real danger of false teachers is not always what they get wrong, but what they get right. This is why discernment is more crucial than ever.
