If all moments of time were expressed all at once before time existed, then it seems to make sense that "the future" has already been determined because it has already been expressed.
If the "script" of all moments in time was "written" ie put into place, all at once, then within linear time the future is essentially pre-written.
Also if you time travel, whenever you go into a moment in the past, you will find that you experience it as though it is the present - as if "now" is 1952. Similarly in the future, no matter what the date, it will seem that "now" it is that time.
This seems to suggest a sense of "fate" or destiny, whereby whatever will happen or is happening or has happened was all written at once, not on a moment-by-moment basis.
The Holy Spirit nevertheless is able to collapse dimensions or segments or time, based on your learning of lessons.
There are references to "all the dimensions of time" in the Course, suggesting that there are perhaps multiple timelines - all pre-written, and you might shift between them.
It is also said that when we separated and made the world, Holy Spirit came with us and had a hand in organizing it. "There are two makers of the world". So now all the stuff we made, that we pre-wrote, has been restructured in some way to lead to heaven.
This all seems to suggest that we're just strapped into some kind of rollercoaster ride with no choices, as though we are just the movie itself playing. If this were the case, there is absolutely no "choice" or freedom in this scenario.
Yet think of Jesus performing miracles, undoing and reversing sickness, overcoming death, becoming free of the script entirely, able to manipulate objects and defy all of the laws that were made by the ego. It would seem that he attained freedom and the flexibility to not be bound by the script. We would say now that He is completely free of it, able to do anything.
So, the script is only in play if you are in the ego and remaining unconscious? Based in the perception that stuff (script) happens to you against your will? How can there be any victimhood script when you are choosing not to be a victim, not to play along?
It's not as though you are forced to be a victim to the same degree and intensity right up till the moment of awakening. And let's remember that events are designed by the one who has your best interests, Holy Spirit.
It is also said there are two scripts. Since Holy Spirit had a hand in reorganizing and repurposing what we made, not just as a 'way of looking at it' but to actually rearrange time and the sequence of events, there was the ego's attempted purpose for what it made, and then there is Holy Spirit's use of it. A use which we need to learn to trust.
If all events here are lessons and we're not supposed to be hanging out in a make-believe world anyway, it seems to suggest we are to simply follow Holy Spirit's plan and trust Him and eventually this will lead to the gates of Heaven.
If we are simply "wearing" a lifetime, like a piece of clothing, for purposes of waking up, to use it as a choice to experience a certain set of events as a certain person, then it doesn't seem quite so restrictive.
Has everything been made already, or can you change anything at all? It would seem you can change things. Miracles, right? Miracles reverse what we made. Miracles undo the script.
