“I fear, wherever riches have increased, essence of religion, the mind that was in Christ, has decreased in the same proportion. Therefore do I not see how it is possible, in the nature of things, for any revival of true religion to continue long. For religion must necessarily produce both industry and frugality; and these cannot but produce riches. But as riches increase, so will pride, anger, and love of the world in all its branches.”
