How do we know God's covenant with His people is true?

The foundation of God's covenant with His people is rooted in Jesus Christ, who was slain from the foundation of the world (Revelation 13:8). This covenant of redemption ensures that all creation is founded on God's promise to save His elect. The consistent theme of Scripture reveals that God's faithfulness to His covenant is unwavering; He remembers His people as He did Noah and fulfills His promises through Christ. The assurance of this covenant is evident in how He carries His elect into the new creation, guaranteeing eternal life and righteousness through Jesus.
