In Christianity, born again refers to a "spiritual rebirth" (regeneration) of the human soul or spirit, contrasted with the physical birth everyone experiences. The origin of the term "born again" is the New Testament: "Jesus replied, 'Very truly I tell you, no one can see the kingdom of God without being born again.'" [Jn 3:3] Source: Wikipedia
