Immortality
ConceptImmortality is the state of being exempt from death and enduring without end, and Scripture speaks of it chiefly as "eternal life," a life it presents as God's gift rather than a natural human possession. The vocabulary is worth noting as an established linguistic fact: the Greek adjective behind "eternal" in these passages is aiōnios, formed from aiōn ("age"), so "eternal life" carries the sense of the life of the age to come as well as life without terminus.
In the Gospel of John, eternal life is both a present possession and a future hope. The text says that whoever believes in the Son "should not perish, but have eternal life" (John 3:15–16), and that "one who believes in the Son has eternal life" while the one who disobeys "won't see life" (John 3:36) — the contrast is between perishing and having life, and it turns on faith in the Son. Jesus says he gives eternal life to his sheep, who "will never perish" (John 10:28), and yet also that he "will raise him up at the last day" (John 6:40). To Martha he says, "I am the resurrection and the life. He who believes in me will still live, even if he dies," and "Whoever lives and believes in me will never die" (John 11:25–26). The passages hold together what might otherwise seem in tension: a life possessed now by believers, and a bodily raising still to come.
Other passages frame the same gift in terms of inheritance and preservation. Acts 26:18 describes an "inheritance among those who are sanctified by faith," and 2 Timothy 1:9 grounds salvation in God's "own purpose and grace, which was given to us in Christ Jesus before times eternal" — the purpose preceding time itself. First Peter 1:3 and 1:5 speak of being reborn "to a living hope through the resurrection of Jesus Christ from the dead," a salvation "ready to be revealed in the last time," guarded through faith; 1 John 2:17 sets the passing world against the one who does God's will and "remains forever." Across these texts, immortality is consistently tied to Christ's resurrection and to faith in him, not to a property humans hold independently.
Christian traditions differ in how they relate this gift to human nature. Much Catholic and Protestant teaching has held, as a matter of theology rather than of the biblical text alone, that the human soul is naturally immortal, so that all people continue consciously after death — the saved in life, the lost in judgment. Others, often called conditionalists or annihilationists (Adventist and some evangelical bodies), argue that Scripture attributes immortality to God and offers it in Christ as gift, so that those who reject the Son genuinely "perish" (John 3:16) rather than existing forever in torment. Eastern Orthodox thought typically frames the matter as participation in God's own life — theosis — so that immortality is a share in divine life granted by grace rather than a possession of the creature. These readings disagree about the fate of the impenitent and about what "immortality" names in human nature, while all of them confess that eternal life is given through Christ and is not something a person secures alone.
