What does the Bible say about the importance of faith?

Ephesians 2:8-9 illustrates the centrality of faith in the salvation experience, stating that we are saved by grace through faith, and this not of ourselves; it is the gift of God. This doctrine underscores the Reformed belief in sovereign grace, showing that salvation is entirely an act of God's grace and not based on human merit. Faith itself is a gift from God, allowing us to trust in Jesus Christ for our salvation. The assurance of our faith is rooted not in our own abilities, but in the work of Christ, who is the author and perfecter of our faith. Thus, understanding the significance of faith is foundational for every believer.
