How does the covenant of grace differ from the covenant of works?

The covenant of grace stands in stark contrast to the covenant of works, which emphasizes human achievement. The latter is based on the flawed premise that humans can earn favor with God through their actions. In contrast, the covenant of grace, as articulated in Hebrews 8:6-13, reveals God's promise to act on behalf of His people, ensuring their salvation through Christ. This shift from 'do' to 'done' encapsulates the heart of the gospel: that Christ's life, death, and resurrection fulfill all the requirements of perfection that the law demands. Therefore, believers are called to rest in this assurance that their salvation is accomplished by Christ alone.
