Remember that pride is the worst viper that is in the heart, and the greatest disturber of the soul’s peace and sweet communion with Christ. Pride was the first sin that ever was.
Pride is the most difficult sin to root out. It is the most hidden, secret and deceitful of all lusts, and often creeps in, insensibly, into the midst of religion and sometimes under the disguise of humility!
— Jonathan Edwards (1703-1758)
