How do we know that the righteousness of God is true?

The righteousness of God is demonstrated through both the Old and New Testament prophecies which point to Jesus Christ, the ultimate fulfillment of God's promise to redeem His people. Romans 3:21-22 elaborates on how righteousness comes through faith in Jesus for all who believe. This righteousness is grounded in God's character and His immutable nature, assuring believers that it is not dependent on human works but rather on divine grace. Therefore, Christians can rest in the certainty of God's righteousness, evidenced through Christ's life, death, and resurrection.
