Why is understanding the covenant of works important for Christians?

The covenant of works sets the stage for the understanding of human depravity and the need for divine grace. By requiring perfect obedience, it emphasizes that no one can satisfy God's demands and that all have sinned and fall short of His glory. This realization serves to redirect our reliance from self-works to the finished work of Christ in the covenant of grace. By acknowledging our shortcomings under the covenant of works, Christians are reminded of their dependence on Christ's righteousness for salvation, thus deepening their appreciation for the grace of God.
