Why is it significant that we are justified by faith?

Justification by faith is a pivotal doctrine in Reformed theology, affirming that through faith in Jesus Christ we are declared righteous before God. Romans 5:1 states, 'Therefore, being justified by faith, we have peace with God through our Lord Jesus Christ.' This illustrates that justification is an act of God’s grace where believers are imputed the righteousness of Christ, not based on personal merit but on Christ's perfect obedience and sacrificial death. This assurance provides believers with profound peace and a secure standing with God.
