Why is the righteousness of Christ important for Christians?

For Christians, the righteousness of Christ is vital because it satisfies the requirements of the law that they cannot fulfill on their own. Scripture reveals that Christ was made to be sin for us, who knew no sin, that we might be made the righteousness of God in Him (2 Corinthians 5:21). This foundational truth assures believers that their standing before God is not based on their flawed attempts at righteousness but upon the perfect obedience of Christ. Through His obedience, believers are cloaked in righteousness, allowing them to have peace with God. Thus, it is through Christ's righteousness, and not their own, that they are justified and accepted by God.
