What is the significance of faith in salvation according to Reformed theology?

In Reformed theology, faith plays a crucial role as the channel through which God's grace is received. According to Ephesians 2:8-9, 'For by grace you have been saved through faith, and that not of yourselves; it is the gift of God.' This emphasizes that even our faith is granted by God's grace, illustrating further dependence on Him for salvation. The example of Abraham in Isaiah 41 serves to demonstrate that faith leads to righteousness before God, not as a work we accomplish, but as the response empowered by the Holy Spirit.
