What does the Bible say about the preservation of the saints?

The preservation of the saints is a foundational doctrine within sovereign grace theology, emphasizing that God maintains the salvation of His elect. Scripture passages such as John 6:39 highlight that all whom the Father has given to Jesus will be raised up at the last day, showcasing God's unwavering commitment to His covenant promises. In Romans 8:28-30, we find a clear depiction of God's divine orchestration in salvation, where those He foreknew are also predestined, called, justified, and glorified, signifying an unbreakable chain in the salvation process. This means that once God has chosen His people, they will never be abandoned or cast away, reinforcing the assurance of eternal security in Christ.
