How does the covenant of works contrast with the covenant of grace?

The covenant of works, represented by Adam, demands perfect obedience to God's law as a condition for life. Adam’s failure resulted in death for himself and all of humanity. In stark contrast, the covenant of grace, unconditionally secured by Christ, offers salvation to the elect through faith, independent of their works. This covenant is characterized by God’s promise to save through Christ’s substitutionary sacrifice, underscoring that salvation is a divine gift rather than a reward for obedience.
