Adam and Eve the first man and woman that God created to live in a paradise on earth, fell away from that state and caused the present world of suffering. Adam gave birth to Eve through the intervention of the Creator. Eve caused the fall of Adam.
This disobedience had to be resolved through repentance. Thousands of years later was born him, who they would call Emmanuel. Jesus was conceived in the womb of his mother Mary through the Holy Spirit without the aid of a human father and born while Mary was yet a virgin.
Thus Eve who was born of the side of Adam, who had caused the fall of Adam, gave birth to the new Adam as Jesus. It was the same energy (soul) that had been given an opportunity to save mankind as Mary & Jesus.
