w63 12/1 pp. 733-734 The Gift of Immortality
Although they will enjoy human perfection, they will still be corruptible because they will still be made of flesh that is capable of decaying or of being destroyed by another creature. They will have the power to live indefinitely, but for them to continue living they will have to keep their bodies supplied with food and water. Without these necessities they would waste away. Such is not the case with the few who are made incorruptible by being given the gift of immortality. Their continued existence is not dependent upon outside sources of energy. God has given them the power to be self-sustaining, just as he is. This is one of the factors that contributes to their being superior to the angels. Their superiority is revealed by Paul’s statement to them: “Do you not know that we shall judge angels?”—1 Cor. 6:3.
The angels have the power of an indefinite life, but their life force is not self-sustaining and indestructible. Immortality was never given to them. This is evident from the fact that the resurrected Jesus was the only one of Jehovah’s creatures who possessed it in the days of the apostle Paul, although angels had been living for a very long time before then.
Gee, Schizm, I have known this one since I was eight years old. I'm disappointed. You did say since 1960, right ? I wonder if you'll come back with "since 1970" next. Gotta love that ever-changing light, eh?
