Blessed be the God and Father of our Lord Jesus Christ, who according to his great mercy became our father again to a living hope through the resurrection of Jesus Christ from the dead,
Hath begotten us again - The meaning is, that as God is the Author of our life in a natural sense, so he is the Author of our second life by regeneration. The Saviour said, John 3:3 that “except a man be born again,” or “begotten again,” (γεννηθῆ ἄνωθεν gennēthē anōthen,) “he cannot see the kingdom of God.” Peter here affirms that that change had occurred in regard to himself and those whom he was addressing. The word used here as a compound (ἀναγεννάω anagennaō) does not elsewhere occur in the New Testament, though it corresponds entirely with the words used by the Saviour in John 3:3, John 3:5,John 3:7. Perhaps the phrase “begotten again” would be better in each instance where the word occurs, the sense being rather that of being begotten again, than of being born again.
