How do we know that regeneration is the work of God?

Regeneration, or the new birth, is the act of God whereby He imparts spiritual life to those who are spiritually dead. The Scripture makes clear that this act is not achieved by human will or effort, but it is solely the result of God's sovereign choice and action. John 1:13 underscores that individuals are not born of human decision or effort, but of God. Similarly, in Ezekiel 37, the Lord declares, 'I will cause breath to enter into you, and ye shall live,' indicating that it is God who initiates and accomplishes the work of regeneration.
