John Flavel (Works, vol. 5, p. 525):
Away with rash uncharitable censures of others, and be more just and severe in censuring yourselves. Away with dry and unprofitable controversies, and spend your thoughts upon this great question, Am I sound, or am I rotten at heart? Am I a new creature, or the old creature still in a new creature’s dress and habit? Beg the Lord that you be not deceived in that great point (your integrity) whatever you may be mistaken in. Pray that you be not given up to an needless, careless, and vain spirit, and then have religious duties for a rattle, to still and quiet your consciences.
