Many rest in the externals of religion and in the outward performance of holy duties. And very often this most effectually deceives men, and more certainly undoes them than open profaneness; as it was in the Pharisee’s case. They hear, they fast, they pray, they give alms—and therefore will not believe their case is bad. Whereas, resting in the work done, and coming short of the heart-work and the inward power and vitality of religion, they fall at last into the burning, from the flattering hope and confident persuasion of their being all set on the way to heaven. Oh dreadful case, when a man’s religion shall serve only to harden him, and effectually to delude and deceive his own soul! ~ A Sure Guide to Heaven by Joseph Alleine
