I am afraid there are Calvinists, who, while they account it a proof of their humility that they are willing in words to debase the creature and to give all the glory of salvation to the Lord, yet know not what manner of spirit they are of... Self-righteousness can feed upon doctrines as well as upon works; and a man may have the heart of a Pharisee, while his head is stored with orthodox notions of the unworthiness of the creature, and the riches of free grace.
