immortality

Jehovah God is “from everlasting to everlasting.” He is immortal. (Psalm 90:2) The first person to whom Jehovah granted the gift of immortality was Jesus Christ. The apostle Paul explains: “Christ, now that he has been raised up from the dead, dies no more; death is no longer master over him.” (Romans 6:9) Indeed, contrasting the resurrected Jesus with earthly rulers, Paul describes him as the only one among them having immortality. Jesus will remain “alive forever.” His life is “indestructible.”—Hebrews 7:15-17, 23-25; 1 Timothy 6:15, 16.
Jesus is not the only one to receive such a gift. Spirit-anointed Christians chosen to rule as kings in heavenly glory receive the same kind of resurrection that Jesus did. (Romans 6:5) The apostle John shows that this privilege is granted to 144,000 individuals. (Revelation 14:1) They too receive immortality. Regarding their resurrection, Paul says: “Flesh and blood cannot inherit God’s kingdom . . . The trumpet will sound, and the dead will be raised up incorruptible, and we will be changed. For this which is corruptible must put on incorruption, and this which is mortal must put on immortality.” Death has no hold on those who receive such a resurrection.—1 Corinthians 15:50-53; Revelation 20:6.
This divine revelation is remarkable indeed. Despite their spirit nature, not even angels were created immortal. This is shown by the fact that those spirit creatures who joined Satan’s rebellion will be executed. (Matthew 25:41) Jesus’ corulers, on the other hand, receive the gift of immortality, which is proof of Jehovah’s unshakable confidence in their faithfulness.
