God would not rub so hard if it were not to fetch out the dirt that is ingrained in our natures. God loves purity so well He had rather see a hole than a spot in His child's garments.
William GurnallAs the eye of the body once put out, can never be restored by the creature's art, so neither can the spiritual eye lost by Adam's sin be restored by the teaching of men or angels. It is one of the diseases which Christ came to cure.
