Spiritual pride is very apt to suspect others, but a humble saint is most jealous of himself. He is as suspicious of nothing in the world as he is of his own heart. The spiritually proud person is apt to find fault with other saints...and to be quick to notice their deficiencies. But the eminently humble Christian has so much to do at home, and sees so much evil in his own heart, and is so concerned about it, that he is not apt to be very busy with other hearts... Pure Christian humility disposes a person to take notice of everything that is good in others, and to make the most of it, and to diminish their failings, but to give his eye chiefly on those things that are bad in himself.
Jonathan Edwards
