Since the beginning of Christianity some have doubted the resurrection, asking how the dead could be resurrected and with what bodies they could return from the grave (1 Cor. 15:35). Based on the Word of God, the author provides clear explanations on several points concerning the soul and the body, Sheol or abode of the "dead", the future of our souls without their body, the future of our bodies after death, explanations based on the death and resurrection of Christ.
