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,
By the resurrection of Jesus Christ from the dead ... This does not deny that Christians are born again through obeying the word of God  (1 Peter 1:22), but refers to the source of that word, Jesus Christ, and the mighty act wrought by God in his resurrection of our Saviour from the tomb, the same being the enabling charter, the vast achievement which made the salvation of people possible.  Thus it is quite correct to say that Christians are born again by the resurrection of Christ from the dead.
