Why is faith important in the context of God's promises?

Faith acts as the essential link between God's promises and the believer's experience. In the sermon, it is noted that faith comes by hearing the Word of God, which emphasizes the necessity of receiving the gospel to truly grasp God's promises. Romans 8:28 provides a clear indication that all things work together for good to those who love God, indicating that faith is a response to God's prior love and election. Believers are called to rest in faith, trusting that God will fulfill His promises, assuring them of their eternal security and the triumph of His purposes.
