How do we know the righteousness of God is necessary for salvation?

The necessity of God's righteousness for salvation is clearly articulated in Romans 10:4, where Paul writes, 'For Christ is the end of the law for righteousness to everyone who believes.' This highlights that our own attempts at righteousness are futile, as fallen humanity cannot achieve the standard required by God. Instead, true righteousness is given to us through faith in Jesus Christ, who has perfectly satisfied the demands of the law. We are called to abandon our self-righteous efforts and instead receive Christ's righteousness by faith.
