We shall never be clothed with the righteousness of Christ except we first know assuredly that we have no righteousness of our own.
John Calvin
1 Pet 2:24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed. The transformation from the old person to the new person is called the born-again experience. Christ nature is lived through us. Paul the apostle said it this way not I but Christ who lives in me Gal 2:20
“Righteousness” is a legal term. It means to have right standing before God. Vine’s Expository Dictionary of Biblical Words defines righteousness as “that gracious gift of God to men whereby all who believe on the Lord Jesus Christ are brought into right relationship with God.”
Nothing can damn a man but his own righteousness; nothing can save him but the righteousness of Christ.
Charles Spurgeon
