Why is the righteousness of faith different from the works of the law?

The righteousness of faith differs fundamentally from the works of the law in that it is based on trust in the sufficiency of Jesus Christ's atonement rather than on human ability to adhere to the law. Romans 4:13-15 outlines this distinction: the law demands perfection, stating that the man who does these things shall live by them, which ultimately leaves all men guilty because none can perfectly fulfill the law. In contrast, the righteousness of faith declares that it is through belief in Christ that one is made righteous. This is empowering, as it liberates believers from the inability to achieve justification through the law's requirements, instead placing their hope in Christ's completed work, which earnestly fulfills the law's demands on their behalf.
