Current thinking is, it depends on the instruction book one's parents gave one.
For Christians, then: if one has followed the two instructions in Romans 10:9, one enters Heaven.
One gets rewards based on works; Revelation 22:12.
This Earth/Heaven realm ends at some point, in a fire.
There's a lot less information, about after that.
Anon just found Aquarian Gospel 105:32-38, specifically 36, which says we get to try this choose-your-own-adventure "book" again. Anon guesses that "each Plank moment" of time, one gets to make choices. Not sure exactly what the "Xbox controller" up in Second Heaven looks like. Or what "I" do; my higher self that is, typing on something while I type on this.
Anon isn't sure if there's a test to enter Second Heaven, at the end of this existence. Might be; also, might only be found in Scripture that we'll have access to, once we're in Heaven.
From Second Heaven, we "buy tickets"/"write contracts" to have experiences here, "in-Earth/Heaven". Thinking it might be like a dream, within the dream Jesus is dreaming in Third Heaven. Jesus the Father that is; He wrote Himself into this book we're living in, in the First Person, and as the First Person; He created everything, see John 1:3.
Second Heaven has so many more experiences for us, also! For one, we might "need to play Earth from every player's perspective" and thus be each of our family members, friends, enemies, etc and this might also include experiencing the duration of eternity as a blade of grass, or an atom combining with many others along the way, or subatomic particle, ghost/spirit/dimensionless point/etc.
Each of these journeys likely has an "Easter egg" of some sort, something hidden for us to find and marvel at, and add to our respective journeys at exactly the right time.
Maybe another Earth, after this one. And if we're in "crater Earth" then there's a ton more land and stories to explore, in this book, before we move on to the next.
Second Heaven might end at some point as well.
With a test to enter Third Heaven.
Which is where we get to create. So anon has heard, from a few sources. Still looking for confirmation of that one in Scripture; Paul writes about it, in 2 Corinthians 12:1-6, although only mentions its existence, really.
The search continues; Proverbs 25:2, which reflects 25:11.
I hope this helps your search. I welcome any correction.
God bless in Jesus name.
