Interestingly, the Chinese word yi, which means righteousness is comprised of two characters, one on top of the other. The character yang which means lamb is placed on top of the character wo which means me (or self or I). When the lamb is placed on top of self, righteousness results.
Our righteousness are akin to filthy rags (Isaiah 64:6) and so on our own merit, we stand no chance. Thankfully, it is not our righteousness that matters. But praise be to God the Father, who made a provision for us to inherit eternal life. When we place our trust in the Lamb of God, Jesus Christ, who takes away the sin of the world (John 1:29) we are imputed righteousness (2 Corinthians 5:21; 1 Corinthians 1:30). When we place our self underneath the Lordship of the Lamb of God, Righteousness (that matters) results.
