I have observed eternity (in the Bible), and gathered from what is known about eternity (in the Bible), and have been informed about eternity (from the Bible), and believe about eternity (what the Bible says).
Given Webster's definition for the word "understand", my post was appropriate and also directly responsive to your question.

to be thoroughly familiar with; apprehend clearly the character, nature, or subtleties of: to understand a trade.
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
