A Saint Indeed

An extended sermon on Proverbs 4:23, calling believers to keep the heart with all diligence. Flavel unfolds what heart-keeping requires, why it is the Christian's supreme daily duty, and offers detailed, compassionate counsel for nine critical seasons of life — including prosperity, adversity, spiritual desertion, temptation, and the approach of death. Rich in Scripture and practical wisdom, this work is a landmark of Puritan experiential piety and pastoral care for the inner life.
