No good thing in ourselves

To crucify this corruption, Providence takes off the bridle of restraint from ungodly men, and sometimes permits them to traduce the names of God's servants, as Shimei did David's. Yea, they shall fall into disesteem among their friends, as Paul did among the Corinthians; and all this to keep down the swelling of their spirits at the sense of those excellencies that are in them. [John Flavel]
