In Latter Day Saints theology, the term spirit world refers to the realm where the spirits of the dead await the resurrection. In LDS thought, this spirit world is divided into at least two conditions: paradise and spirit prison:
Paradise includes the spirits of the just, who had been faithful in the testimony of Jesus while they lived in mortality.
Spirit prison is the condition of the spirits of the wicked ... the ungodly and the unrepentant who had defiled themselves while in the flesh ... the rebellious who rejected the testimonies and the warnings of the ancient prophets.... The latter will continue to receive gospel teaching and be given the opportunity to repent, though their disposition toward repentance will only change as they recognize and accept gospel truths and believe in Jesus Christ.
