"This is the world of time, where all things end."
This should be fairly easy to understand. Time is the idea that what seems to be here now, cannot remain. It must change. It must stop being what it is.
This leads to realizing that time does not allow anything to be permanent. Everything becomes temporary. That means everything is forced to come to an end. Which means everything dies. And both birth and "death" are now part of a whole system of death, in which everything has the mark of death upon it, even from the outset of "new life".
Time is the very thing which seems to produce growth and change. It is the seeming driving force behind the beautiful flowers that grow from seed and bloom and share their fragrance for a little while, before time just as easily forces them to stop being this way, enforcing death and decay.
Time does not allow anything to remain as it is. It is an attack upon the idea of eternal life. It is a notion that what has always existed no longer exists, being the destruction of God himself. It essentially places God into the past and kills him off and converts him into some other mangled form. And even if it reflects glimpses of God it will only offer them temporarily.
The world, by which I mean planet Earth, but also the solar system, the galaxy and all the galaxies/interstellar objects, are all governed by time. Every particle of matter is governed by time. This means that everything in this system HAS to change, which produces a constant state of movement and the impossibility of perfect stillness. Nothing is ever allowed to rest and be truly at peace. Even the rocks sitting there for many years are gradually being changed and converted against their will. Nothing in the world or this "universe" can escape this.
"At no SINGLE instant does the body exist at all. It is always remembered or anticipated, but NEVER experienced just now. Only its past and future make it seem real. Time controls it entirely. For sin is never present."
Since time enforces change, it enforces ends, which means it enforces death. Don't be deceived in thinking there are exceptions to this. Absolutely everything in the world has the mark of death upon it and will die, unless perhaps there is an interventional miracle from another world beyond the laws of time and space.
Time wants you dead. The very thing which seems to allow your body to move and change is also the very thing which is seeking its destruction. Time is the very thing which permits birth but also death. It is not picky about what state anything is in. Jesus is telling me to use the word "unscrupulous" here.
In a world of time, all things end. There can at best be seeming periods in which things seem to be fairly consistent, fairly constant, or even long-lasting, but they are never endless, and a time will come when they will end. These temporary illusions of almost-permanence mask the fact that the whole system is still gradually destroying itself. And if you fall for the illusion of believing that its presentation of "life" is at its maximum, you are blind to the fact that even the living are partly dead.
"There IS no life outside of Heaven. Where God created life, their life must be. In ANY state apart from Heaven, life is illusion. At best, it SEEMS like life; at worst, like death. Yet both are judgments on what is NOT life, equal in their inaccuracy and lack of meaning."
Since there is no real eternal life outside of heaven, and Earth is a realm technically "outside" of heaven, or at least believed to be, it is not a world where there is real life, or maximum life. It is a world of death. This is because separation from heaven means the inducing of time and space, which is delay or avoidance or denial of reality.
So this whole system is set up for death. All the time it is devouring itself. All the time it is working on destroying itself. Sometimes it presents illusions of birth and newness and growth and prosperity, only to GUARANTEE that at some point it will just as easily take it all away without blinking an eyelid. And to some that may come as a shock or surprise, or something long put-off and avoided, as if it is not going to happen. But look at how everything you ever had in the world came to an end.
Essentially change is death. Although of course in this world it seems that you must change in order to "live", because the whole system is backwards. But change does not allow the immortal to remain immortal, and the eternal are brought into question by it. Without time you would live forever, but with time you are destined to be destroyed.
Jesus suggests that there is no hope of escape from death IN the world. You cannot stay IN time, and have there be no death. Time and space are both attacks on reality's nature. They cannot be combined or coexist. You cannot keep time, along with bodies moving and growing and so on, and still expect there to be no death. "Seek not ESCAPE from problems here. The world was made that problems could not BE escaped."
Read it carefully because it's telling you that there is NO WAY EVER to escape from problems WITHIN the world. The only way ultimately is to transcend it, rise above it, and eventually leave it. The whole system of spacetime will always entail death and destruction. It will not ever be heaven or offer eternal life. It cannot therefore save you and cannot save you from itself.
You HAVE to find a better way - another world, not of you, which God created perfect. The ONLY HOPE that you truly have is that this world is not real and is thankfully NOT doing what it appears to be doing. Do not be deceived into thinking that this world can ever be dressed up as a living world or a permanent world or a world of hope or a world of salvation and happiness. It is nothing and will never be true. All you really want is God.
"It might be worth a little time to think once more about the value of this world. Perhaps you will concede there is no loss in letting go all thought of value here. The world you see is merciless indeed, unstable, cruel, unconcerned with you, quick to avenge and pitiless with hate. It gives but to rescind, and takes away all things that you have cherished for a while. No lasting love is found, for none is here. This is the world of time, where all things end."
