immortality, incorruption, sincerity

“Immortality (ἀθανασία)” From Concise Bible Dictionary:

The deathless state which stands in contrast to the mortality of man, and which the “mortal” will “put on” when “changed” (1 Cor. 15:53-54). God only has in Himself immortality, being the fountain and source of life for all things (1 Tim. 6:16). In Romans 2:7 and 2 Timothy 1:10 the word is (ἀφθαρσία, 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 (Gen. 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.

“Incorruption (ἀφθαρσία)” From Concise Bible Dictionary:

The state which the bodies of the dead in Christ (now going to corruption in their graves) will have at the resurrection. When this takes place, and the mortal shall have put on immortality, death will be swallowed up in victory! (1 Cor. 15:42-54). In Romans 2:7 and 2 Timothy 1:10 the word is the same as the above, and should be translated “incorruption” instead of “immortality.”
