"It is a proof of our depravity that good habits are much more easily lost than acquired, whereas bad habits are acquired with ease but laid aside with difficulty."
"One of the greatest contradictions in human nature, and the very strongest proof of our depravity is, that the communication of extraordinary measures of divine comforts, which in their own nature have a direct tendency to humble, has, through our corruptions, sometimes a contrary effect...."
--John Newton, Letters of John Newton
