What does the Bible say about the righteousness of God's law?

The righteousness of God's law is central to understanding salvation and the gospel. In Matthew 5:20, Christ asserts that unless our righteousness exceeds that of the scribes and Pharisees, we cannot enter the kingdom of heaven. This indicates that human morality, defined as moral behavior, falls short of God's perfect standard of righteousness. True righteousness, as defined in Scripture, is a perfect satisfaction of God's law and justice, and without it, we are guilty of sin. Only Christ, through His death and obedience, fulfills this righteousness, which is credited to all His chosen people, highlighting the necessity of His law-keeping to redeem the unrighteous.
