How do we know that the new birth is the work of God?

The scripture emphasizes that the new birth, or regeneration, is exclusively the work of God. In Ephesians 2:1, we see that we were 'dead in trespasses and sins,' highlighting our inability to initiate our own salvation. Only God can impart spiritual life, just as only He has the authority to create physical life. The act of being 'begotten' in the spiritual sense is entirely a divine operation. Regeneration requires the power of God to give faith and repentance, and through His Word, as described in 1 Peter 1:23, we are 'born again, not of corruptible seed, but of incorruptible, by the word of God.' This unyielding scriptural truth showcases that no human effort can bring about the new birth; it must be from God alone.
