Why is Christ's righteousness important for believers?

Christ's righteousness is paramount for believers as it is the only basis for our acceptance before God. Romans 3:22 teaches that the righteousness of God comes through faith in Jesus Christ to all who believe. Our own righteousness is likened to filthy rags and cannot stand before a holy God. It is only through Christ's perfect obedience and sacrifice that we are justified. Thus, believers are clothed in His righteousness, which grants us peace with God and the assurance of eternal life. Without Christ's righteousness, we would stand condemned under the law.
