"Men that are proud and self-conceited are ignorant of the excellencies of others; and this is a cause why they are ignorant of their own comparative meanness. For instance, they are ignorant of the glory and greatness and excellencies of God and so don’t know the difference between him and them. And they are blind to others’ excellencies, because they have no spirit of love to their neighbor. They are ignorant of their own mistakes, and that makes them think themselves wise. [They are] blind to their own faults and blemishes. They don’t see the evil and hatefulness of many things in themselves; which if they did they would be sensible that they are vile and unworthy. If men saw what a sinful and vile
heart they have, if they saw the evil of their sinful actions, they would be full of shame and confusion would cover them, instead of being lifted up in a high thought of themselves."
