Change

Change - everything changes.
We grow up and age as the years go by. The tiny acorn changes into a giant oak tree. The clouds are shaped and moved by the winds. Everything changes.
However, what CAN change is not what it is itself that very moment and what it CAN be at the same time. I can't be me right now and me 5 years from now at the same time. It is either or. Also, things can not bring themselves into being, and until it becomes whatever it is supposed to be, it does not yet exist, and therefore can not cause anything. (Did I lose anyone?)
All things change, and all change is the result of an act or force that caused the change. Nothing can give itself what it does not have, nor have something that it's supposed to have in the future in the present. "The result of change can not exist before the change" (Kreeft). All have a potential to change, but something needs to act upon it or cause it to change.
[ex.]: bodies move (change) because of the will
Question to consider: Are the things causing change also changing themselves? (pretty much a rhetorical quetion). If so, then everything is this big chain of cause and effect, where everything needs to be acted upon by something above/outside itself in order to change. The entire universe is changing and is the sum of all these moving/changing things. Therefore, there has to be something outside of the universe, causing it to change, in order for it to do so. A transcendent being. The universe is dependent on and changing with respect to three things: matter, space, and time. This being must then be outside of matter, space, and time. The being is not a changing thing, for that implies something outside of it to cause it to change, but the being is an unchanging Source of change.
