How do we know that God's grace fully saves us?

The doctrine of sovereign grace insists that God's grace is not contingent upon human effort or decision; rather, it is an act of divine mercy. As mentioned in the sermon, God's word is clear that grace is freely extended to sinners just because He desires to save them, not because of any merit on their part. Ephesians 2:8-9 reminds us that we are saved by grace through faith, and that this is not our own doing; it is the gift of God. This truth emphasizes that salvation is solely rooted in God's sovereign will and grace.
