While this word sounds the same as immoral, it is very different. Immortality literally means “no death” in Greek. Another related word which can be translated immortal describes the body not decaying, but lasting forever. Because of sin we will all die, and our bodies will decay in the grave. But the Apostle Paul reminds us that because Jesus defeated death through His death on the cross, we have the hope of the resurrection and a new life in the resurrection. When our bodies are raised from death, we will be raised incorruptible and immortal – never to decay nor to die. This is the Christian’s confidence!
