Why is understanding grace and faithfulness important for Christians?

Understanding grace and faithfulness is crucial for Christians as these concepts highlight God's unchanging character in His redemptive plan. The sermon illustrates that grace, as God's unmerited favor, and faithfulness, as His unwavering commitment to His covenant, formed a partnership at the cross. Grace declared it would make the payment for our sins, and faithfulness promised to reclaim us. This divine agreement assures us that God is both just and merciful, giving us hope for salvation and transformation.
