What does the Bible say about the covenants?

The scripture delineates between two main covenants: the covenant of works established with Adam, which demanded perfect obedience, and the covenant of grace, which assures salvation through faith in Christ. The covenant of works is based on human performance, stating that if one obeys God's laws perfectly, they will be saved. In contrast, the covenant of grace reveals that salvation is a divine promise from God, fulfilled through Jesus Christ, who accomplished what we could not. Understanding these covenants is crucial for comprehending God's redemptive plan as revealed throughout the entire Bible.
