Why is trusting in Christ's righteousness essential?

The essence of salvation lies in recognizing that our righteousness is inadequate before a holy God. The parable of the Pharisee and the publican illustrates this critical contrast; while the Pharisee relied on his works, the publican depended on God's mercy (Luke 18:10-14). Isaiah 64:6 starkly states that all our righteous acts are like filthy rags. Therefore, placing faith in Christ's perfect righteousness is vital for justification, as He fulfills the law and pays for our sins. Only through Jesus can we stand justified before God, as seen in 1 Corinthians 1:30, where it describes Christ as our righteousness.
