Why is being clothed in Christ's righteousness important for Christians?

Christ's righteousness is often depicted as a garment that believers wear, symbolizing their acceptance before God. In Matthew 22:12, the necessity of the wedding garment, which represents Christ's righteousness, illustrates that without His righteousness, there is no entrance into God's kingdom. This concept emphasizes that salvation and acceptance by God are solely dependent on Christ's merits, not our own. Believers can approach the throne of grace confidently because they are seen through the lens of Christ's perfect righteousness, which was acquired through His sacrifice.
