The Pilgrim: Faith vs. Presumption

The design of Satan is to tell the presumptuous, that their presuming on mercy is good; but to persuade the believer, that his believing is impudent bold dealing with God. I never heard a presumptuous man in my life fay that he was afraid that he presumed ; but I have heard many an honest, humble foul say, that they have been afraid that their faith has been presumption. -John Bunyan, The Jerusalem Sinner Saved
