Sasha.......you concluded saying, "What a clever design..."
Men (Men = Mankind / Male and Female) have created many elaborate systems of thought to ward of the sting of death.
The one you suggest is neither original or exclusive.
I would add that most of us recoil at the prospect of dying for any number of legitimate reasons. It brings an end to everything we are are involved with during our lives...family, careers, hobbies, recreation, etc.
And it's interesting you suggest that the differences among individuals as to what they know or sense or have the ability to understand is the result of the number of times they have been 'recycled'.
However, the fundamental problem with your suggestion is that men are clearly divided into two basic catagories:
The one has accepted the Bible as God's word to mankind and have accepted the Bibles Author as the One true God. Experiencially they have found God true through the new birth and believe the entire Bible is God's blueprint for their lives.
The other either through ignorance of or choice does not believe in the Bible or the God of the Bible.
To the second group your notion of repeat lifetimes might appear a clever one. For one thing it allows them to think that, perhaps,they can pick up where they left off. So only briefly are they leaving everything behind.
For the first group the idea falls flat on it's face.
In Hebrews Chapter 9 Verse 27 we read, "And it is appointed unto men once to die,but after this the judgement."
Once to die......For the Christian, there are no returns to see if one can do better the second-or third or forth,etc. -times. "One life...'twill soon be past...Only what's done for Christ will last." No deposit,no return sort of thing.
I will add here that one of the things I believe about the statement "The truth will set you free" is that it does just that. In the case of the topic you mention.....the truth frees me from having to wonder and speculate and guess and revise, etc. concerning the matter of death.
Those without this belief has nothing left but to imagine and create alternatives to the idea of dying...anything to avoid what they know is inevitable.
An example, when I was in the military I had a friend who had convinced himself that death was the end. Nothing on the other side of death's door. Only nothingness. No amount of discussion could change his mind. I haven't seen him in many years. Don't know if he yet inflexible in his position.
So then here we have two imagined methods of avoiding dying and facing the living god who created us. 1.Recycling and 2. Nothingness.
For me....I prefer the true to the false and/or imagined.
For me....God is true. Yesterday, today and forever.
If I am not mistaken, this still leaves us on both sides of the fence. But as long as you don't mind,and as long as we are on the living side of our existence,we can talk over the fence.
Have a good day.
