Why is it important for Christians to rely on Christ for righteousness?

For Christians, the reliance on Christ for righteousness is essential because it recognizes the reality of our sinful nature and inability to meet God's holy standards. As Paul teaches in Galatians 2:21, 'I do not frustrate the grace of God: for if righteousness came by the law, then Christ is dead in vain.' This underscores the futility of seeking righteousness through our deeds. By understanding that all our righteousness is in Christ, we embrace the freedom from sin and condemnation. This reliance transforms our hearts and leads us to live lives motivated by love for God rather than fear of failing to meet the law's requirements, establishing us in a relationship of grace.
