Why should Christians rely on God's work for righteousness?

In Reformed theology, reliance on God's work for righteousness is fundamental to our faith. Romans 3:20 emphasizes that through the law comes the knowledge of sin, signifying that our attempts to achieve righteousness through works are futile. Instead, righteousness comes through faith in Jesus Christ, who fully satisfied the law's demands. This truth liberates believers from the burden of performance-based acceptance before God, allowing us to embrace the gift of righteousness imputed to us through Christ. By resting in His work, we acknowledge that all glory and credit belong to Him alone and not to our own fallible efforts.
