More from my reading of the Journal of John Wesley:
The more I converse with this people, the more I am amazed. That God hath wrought a great work among them is manifest; and yet the main of them, believers and unbelievers, are not able to give a rational account of the plainest principles of religion. It is plain, God begins his work at the heart; then the inspiration of the highest giveth understanding.
Over 260 years later, I do not think that things have changed much.
