Jeremiah used the term from day 1 in Genesis when the earth did not yet have features such as mountains, canyons, lakes etc...The earth at that point was formless and still empty / void. But over the next few days, God continues to form and fill that earth
Hypothetical situation...
Let's say I'm God creating the Earth for the first time.
As God, I exist outside Time and Space.
The very instance I create the Earth, it's destroyed.
Kind of like an experimenter turning on the power to his creation and it goes 'poof' with lots of smoke and blown electronics.
What happened? Why did the Earth suddenly become 'void' as soon as I created it?
Because Time played itself out in that very moment.
All possibilities occurred in a twinkling of an eye.
So what caused the Earth to become destroyed?
I submit to you that we are finding the answer to that in slow motion.
We will one day discover that Mankind and Satan are to blame.
In other words, Mankind finally found a way to enable Satan to go back in time to try and change things in his favor.
Back to the Garden of Eden. That's how he got there. Time Travel.
As soon as God created Earth, there was Satan. Just like that.
He came from the future, and destroyed it in the process.
Believe it or not, I have the verses to back all of this up.
Someday in another thread I'll present my argument more thoroughly.
Time used to go much faster a long time ago. It has slowed down considerably.
That's where 6 days fit in.
Too much to discuss right now, and I don't want to derail your fun thread.
