What does it mean to be clothed with the righteousness of Christ?

To be clothed with Christ's righteousness is to receive His perfect righteousness through faith, as clearly illustrated in Zechariah 3:4 where Joshua, despite his filthy state, is given clean garments. This act symbolizes God's grace that removes our iniquities and replaces them with the righteousness of Christ. Romans 3:22 confirms this by stating that the righteousness of God comes through faith in Jesus Christ for all who believe, highlighting that this righteousness is not based on human achievement but on divine grace alone.
