Pride is the worst viper in the heart. It is the first sin that ever entered into the universe. It lies lowest of all in the foundation of the whole building of sin. Of all lusts, it is the most secret, deceitful, and unsearchable in its ways of working. It is ready to mix with everything. Nothing is so hateful to God, contrary to the spirit of the Gospel, or of so dangerous consequence. There is no one sin that does so much to let the devil into the hearts of the saints and expose them to his delusions.
