This is a fresh restatement of the case for the preservation of the saints, especially valuable in light of the insecurity of much of postmodern life. The book captures the dynamic interplay in the Old Testament between the themes of preservation and apostasy and teaches readers how to understand the New Testament teachings of Jesus and his apostles. Understanding that it is God, in his grace, power, and faithfulness who saves and keeps his people for final salvation brings them stability, gratitude, and confidence to live for his glory.
