(1 Timothy 6:16) Immortality will be given as a great reward to faithful Christians and to none other of the human race.

Such Christians who live and continue faithful until death are promised the divine nature, immortality, the crown of life.
(2 Peter 1:4; 1 Peter 1:3,4; Romans 2:7; Revelation 2:10) We may be sure that a man does not seek that which he already possesses; and the apostle Paul plainly says: "Seek for ...

immortality".

And again he says to those who will be faithful Christians: "This mortal must put on immortality".
(1 Corinthians 15:53) If a soul, a man, were already immortal, he could not subsequently _put on_ immortality.

No one of the human race will ever be made immortal except the faithful Christians.
