How do we know regeneration is a gift from God?

The doctrine of regeneration as a gift from God is rooted in passages like John 1:12-13, where it asserts that those who receive Christ are born not of blood, nor of the will of the flesh, nor of the will of man, but of God. This highlights that our new birth is not the result of human decision or merit but solely God's sovereign grace. The transformative action of the Holy Spirit in the believer's life demonstrates the necessity of divine intervention for salvation, illustrating how faith and repentance themselves are gifts provided in the experience of regeneration.
