Your answer is nonsense. I did not ask you what you believe. If I had asked you what you believe it might have made sense to offer quotes. I asked you what you *understand*. I'll ask it a third time: are you claiming to *understand* eternity?
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.
