So Much Home-Work

Spiritual pride is very apt to suspect others; whereas a humble saint is most jealous of himself; he is so 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, that they are low in grace, and to be much in observing how cold and dead they be, and crying out of them for it; and to be quick to discern and to take notice of 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 others' hearts; he complains most of himself, and cries out of his own coldness and lowness in grace, and is apt to esteem others better than himself.
~Jonathan Edwards
