Flavel’s book explores salvation’s transformative effects on the heart. In the first two of the book’s five sections, Flavel describes how Christ and the Holy Spirit prepare a person to receive God’s saving grace. Following this, he describes how truly convicting the effects of the preparation can be, and how this conviction leads people to emerge stronger after struggling through despair and guilt. Overall, The Method of Grace is a wakeup call. Flavel challenges Christians to examine themselves and, instead of hiding them, let their wrongdoings horrify them so that they may truly appreciate God’s mercy, grace, and love.
