It is a natural state of being for unfallen beings to have their existence subordinate to gods spirit and therefore be eternal there is no reason for their existence to be finite ------------ Bowral, On this we agree. Faithful angels can live on eternally as will obedient mankind here on earth.
(Psalm 37:29) The righteous will possess the earth, And they will live forever on it. This however is different to being granted immortality.
The expressions “immortal” or “immortality” do not occur in the Hebrew Scriptures, which do show, however, that Jehovah God, as the Source of all life, is not subject to death, hence, is immortal. (Ps 36:7, 9; 90:1, 2; Hab 1:12) This fact is also emphatically stated by the Christian apostle Paul in referring to God as “the King of eternity, incorruptible.”—1Ti 1:17. The Greek word a·tha·na·si'a is formed by the negative prefix a followed by a form of the word for “death” (tha'na·tos). Thus, the basic meaning is “deathlessness,” and refers to the quality of life that is enjoyed, its endlessness and indestructibility. (1Co 15:53, 54 ; 1Ti 6:16 ) The Greek word a·phthar·si'a, meaning “incorruption,” refers to that which cannot decay or be corrupted, that which is imperishable.—Ro 2:7; 1Co 15:42, 50, 53; Eph 6:24; 2Ti 1:10.
