Work #2 of God in the New Birth: God raised Jesus from the dead.
"Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead,to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you." (I Peter 1:3-4)
"The new birth is something that happens in us when the Holy Spirit takes our dead hearts and unites us with Christ by faith so that His life becomes our life. So it makes sense that Jesus must be raised from the dead is we are to have new life in union with Him."
