How do we know true saving faith is given by God?

In the sermon, it is emphasized that spiritual faith does not come from our natural abilities but is a gift that God imparts to those whom He chooses. This is rooted in Ephesians 2:8-9, which states, 'For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast.' This passage reinforces that saving faith allows individuals to recognize their need for Christ and compels them to seek Him actively. The case of Bartimaeus, who was physically blind yet exercised faith when he called out to Jesus for mercy, illustrates how divine faith operates in those who are spiritually blinded.
