What is the significance of the righteousness of God?

In Reformed theology, the righteousness of God holds profound significance as it pertains to His character and our salvation. God's righteousness reveals His absolute holiness and moral perfection, serving as the standard against which all humanity is measured. Because mankind is incapable of achieving righteousness on its own, God provides it through faith in Jesus Christ. This is central to the gospel message, as expressed in 2 Corinthians 5:21, where it states, 'For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.' Thus, the righteousness of God not only condemns but also offers justification and life to believers who trust in Christ’s redemptive work.
