Why is the concept of being justified by faith important?

Justification by faith is critical in Reformed theology as it highlights that no one can achieve righteousness through their deeds. Romans 3:28 teaches that justification comes through faith in Jesus Christ alone. This principle emphasizes the futility of relying on our works for salvation, as all have sinned and fall short of God's glory. Instead, we must depend on Christ's righteousness as our only hope. This understanding deepens our appreciation for the grace of God and affirms our complete reliance on Christ for salvation—the foundation of our faith.
