How do we know God's covenant faithfulness is true?

The faithfulness of God to His covenant is grounded in His immutable nature. Throughout Scripture, we see a consistent pattern of God's promises coming to fruition, often highlighted by the repeated refrain that His mercy endures forever. For example, in Isaiah 55:3, God promises an everlasting covenant marked by the 'sure mercies of David.' This ongoing faithfulness is not merely historical; it is experienced by believers today as they witness God's steadfast provision and grace in their lives, reinforcing their faith in His unchanging character.
