How do we know that God's covenant is unbreakable?

The assurance of God's unbreakable covenant is clearly expressed in Judges 2:1, where God states, 'I will never break my covenant with you.' This promise signifies God’s unwavering commitment to His people, despite their failings and rebellion. Throughout the Old Testament, particularly in the books of Exodus, Deuteronomy, and Numbers, we see God's longsuffering and grace toward Israel, even when they repeatedly broke their end of the covenant. This is further illustrated through the example of a remnant being preserved for His glory, as noted in Isaiah 1:9. God's faithfulness stands independent of human failure, providing a foundation for believers to trust in His covenantal love and mercy.
