Immortality means life without death anytime in the future. God is immortal. The souls of people are immortal though their bodies are not. All people can die in a physical sense but they continue on after death. Therefore, it is the soul that is immortal. However, after the return of Christ and the resurrection, the Christians' bodies will also become glorified and immortal (1 Cor. 15:50-58). The wicked will likewise be resurrected to immortality but they will be cast into hell for eternity.
