And I myself also am persuaded of you, my brothers, that you also are full of goodness, filled with all knowledge…
"Of his extreme humility, I experienced an instance which at once astonished and embarrassed me. One day, in conversation, Mr. Wilberforce kindly gave me some advice. I expressed my thanks, and said how much I should feel indebted if, in conversation or correspondence, he would at all times be my counsellor, and, if necessary, correct me, and point out my faults. He suddenly stopped (for we were walking together), and replied, 'I will; but you must promise me one thing.' 'With pleasure,' I answered, little thinking what it was. 'Well, then,' continued Mr. Wilberforce, 'in all your conversation and correspondence with me, be candid and open, and point out my faults.'"
(Memoir of Wilberforce.)
