Psalm 119:137, 138, 142, 144 all were written about the Lord and His righteousness and His word being righteous ~ interlocking oneness. Verse 137 says, “Righteous are You, O Lord…” Verse 138 says, “Your testimonies…are righteous and faithful.”

Verse 142 says, “Your righteousness is an everlasting righteousness…” Verse 144 says, “The righteousness of Your testimonies is everlasting…” 2 Corinthians 5:21 says that we are the righteousness of God in Christ.

Romans 3:10 says, “…There is none righteous, no, not one…” Isaiah 64:6 says, “But we are all like an unclean thing, and all our righteousnesses are like filthy rags…” Those two verses were our state before salvation. By His grace, with no works on our part, we are clothed with His robe of righteousness in exchange for our filthy rags. 

God’s word is the embodiment of His righteous character. As we bring it into our hearts, we are transformed from the inside out ~ partakers of His nature of righteousness.
