And this righteousness from God comes through faith in Jesus Christ to all who believe. There is no distinction, — Romans 3:22

The righteousness of God through faith in Jesus Christ for all who believe. Not a righteousness you produce, but one you receive. He who knew no sin became sin for us so we might become the righteousness of God in Him. Christ redeemed us from the curse of the law by becoming a curse for us. He saved us not by works of righteousness we'd done, but according to His mercy.
