May God’s grace give you the necessary humility. Try not to think — much less, speak — of their sins. One’s own are a much more profitable theme! And if, on consideration, one can find no faults on one’s own side, then cry for mercy: for this must be a most dangerous delusion.

C. S. Lewis (1898-1963) English writer, literary scholar, lay theologian [Clive Staples Lewis]
