I submit that, if there are such things as timelines they are strictly related to level of being. Eternity is orthogonal to time.
Heaven is within you. Now what?
Earth is a being with its own experience of time and, of which you are a part of the thin film of organic life covering It which transmutes impressions between It, the planets and the starry world.
Really? Did Jesus not say "The Kingdom of God is within you"?
Are you fukin kidding me?!
I'm sorry, wrong timeline - HAHAHAHA!
Did Jesus not say: "Could you not stay awake one hour?"
Sin is missing the mark as a man, in the full meaning of the term.
