How do we know that salvation comes from God's covenant?

The assurance of salvation through God's covenant is affirmed in Scripture, notably in 2 Samuel 23:5, where David recalls the everlasting covenant made with him. This covenant, established before the foundation of the world, reveals that our salvation is not contingent on human actions or decisions but purely on God's grace and purpose. In historic Reformed theology, this covenantal perspective provides comfort and security, reminding believers that their standing before God is not based on their faithfulness but on His promise and faithfulness. Furthermore, the New Testament reinforces this truth, especially in passages like Hebrews 8:6-13, where God promises a new covenant that provides forgiveness and restoration to His people, illustrating that salvation has always been God's work.
