How do we know grace is irresistible?

The doctrine of irresistible grace asserts that when God wills to save someone, He overcomes all resistance in that person's heart. The preacher emphasizes that accepting Christ is not a matter of human choice but a glorious act of divine sovereignty. Just as we do not contribute to our physical birth, we do not contribute to our spiritual birth. Ephesians 2:1-5 states we were dead in our trespasses before being made alive in Christ. This transforming work of grace is irresistible to the elect, ensuring that they will come to faith without the option to refuse Him.
