How do we know that faith is a work of God?

The sermon emphasizes that true faith is a gift from God, not a work we can accomplish on our own. As stated in 1 Peter 1:21, our faith is rooted in the knowledge of God through Jesus Christ. It is God who enables us to believe and empowers our trust in Him. Additionally, in Galatians, Paul reveals that faith is a response to God’s revelation in us. So, the very act of believing is itself an evidence of Christ's work within us and not merely a personal endeavor, pointing to the necessity of divine intervention in our lives for true belief to occur.
