Immortality,
aqavasia. The deathless state which stands in contrast to the mortality of man, and which the 'mortal' will 'put on' when 'changed.' 1 Corinthians 15:53, 1 Corinthians 1:15. God only has in Himself immortality, being the fountain and source of life for all things. 1 Timothy 6:16.In Romans 2:7 and 2 Timothy 1:10 the word is afqarsia, not 'immortality,' but 'incorruption.'
The immortality of the soul is plainly revealed in scripture. God breathed into Adam's nostrils the breath of life, and he became a living soul (Genesis 2:7), which is quite different from anything said of a mere animal. The Lord, when showing the Sadducees that God is not the God of the dead, but of the living, added "for all live unto [or 'for'] him (Luke 20:38), though as to the body they may have died.
