How do we know faith is a work of grace?

Faith is fundamentally an acknowledgment of our own weakness and a recognition of Christ's sufficiency. In the sermon, it is emphasized that faith is not a contribution on our part but a miraculous work performed in our hearts by God. It is this divinely bestowed faith that turns our hearts toward God, leading to genuine repentance and a turning away from idols. This dynamic relationship reveals that our faith relies solely on Christ's righteousness, supported by the assurance provided by the Holy Spirit. Ultimately, our faith is a testament to God's grace at work within us, making it evident that we are dependent on Him for salvation and hope.
