So that Christianity is so far from leaving us to live in the common ways of life, conforming to the folly of customs, and gratifying the passions and tempers which the spirit of the world delights in, it is so far from indulging us in any of these things, that all its virtues which it makes necessary to salvation are only so many ways of living above and contrary to the world, in all the common actions of our life. If our common life is not a common course of humility, self-denial, renunciation of the world, poverty of spirit, and heavenly affection, we do not live the lives of Christians.
