Resurrection is the concept of coming back to life after death. In a number of ancient religions, a dying-and-rising god is a deity which dies and resurrects. The death and resurrection of Jesus, an example of resurrection, is the central focus of Christianity.
As a religious concept, it is used in two distinct respects: a belief in the resurrection of individual souls that is current and ongoing (Christian idealism, realized eschatology), or else a belief in a singular resurrection of the dead at the end of the world. The resurrection of the dead is a standard eschatological belief in the Abrahamic religions.
Some believe the soul is the actual vehicle by which people are resurrected.
Christian theological debate ensues with regard to what kind of resurrection is factual – either a spiritual resurrection with a spirit body into Heaven, or a material resurrection with a restored human body. While most Christians believe Jesus' resurrection from the dead and ascension to Heaven was in a material body, a very small minority believe it was spiritual.
There are documented rare cases of the return to life of the clinically dead which are classified scientifically as examples of the Lazarus syndrome, a term originating from the Biblical story of the Resurrection of Lazarus.
