The internet is your friend:
the meaning of the word incorporeal
the meaning of the word corporeal
And so I ask you specifically, do you completely "grasp" the meaning of eternity - do you fully "comprehend" all that eternity contains, can you describe the nature and extent of eternity, can you describe, from experience (are you familiar with) the incorporeal and corporeal substance as well as the light of eternity?
And if so, please do
However, your experience-based faith obviously can't provide answers to the same questions you asked of me.
And...eternity would make a great topical Bible study. I suggest that you undertake such a worthy endeavor.
But what I can grasp is what the Bible makes clear...It is appointed unto man once to die and then to be judged. First, is my name/your name, written in the Lamb's Book of Life (by faith in Christ). Second, we all will have to give an account for what we did in life ("the things done in the flesh" is what scripture says).
So...given what I know the Bible says about eternity...spirit or flesh doesn't rank right up there in the eternity equation for me.
Have a good Thanksgiving!
