Why is faith essential in the Reformed perspective?

In the Reformed perspective, faith is crucial because it serves as the instrument by which we receive God's grace. It allows us to lay hold of Christ's righteousness, setting aside our efforts to achieve salvation through works. Ephesians 2:8-9 emphasizes that we are saved by grace through faith, not of ourselves, underscoring our complete dependence on God’s mercy. The act of believing is a gift from God, assuring us of our justification and standing in Christ (Romans 5:1). Therefore, faith is not simply intellectual assent but a profound trust and reliance on Christ for salvation.
