Since Ecclesiastes many people have noticed that in this mortal life on earth - all worldly things, all possessions, all relationships are subject to change, are transient - nothing can be held-onto.
My response is to say that this is a feature, not a bug, of mortal life; but others (with different metaphysical assumptions) cannot or will not give up the search for something which is permanent, unchanging, solid, perfect, complete - in this mortal life.
That pursuit leads to 'negative theology' - because the only thing that can be held onto forever without change or risk of loss; the only thing we can be sure of keeping is... nothing.
In other words, this leads to a theology of absolute abstraction - probably a deistic, impersonal life-philosophy of one-ness - as seen in so much of Eastern thinking. If one can persuade oneself that one is wholly satisfied with Nothing - then one can indeed get it, even in this mortal life.
If, one the other hand, we accept that mortal life is about change; then we can see that it is about Love; and love is not a possession to be held unchanged, nor is love a state that we want to hold-onto unchanged - but love is a commitment that we can build-around and build-from.
Christians make a commitment to love when we follow Jesus Christ through death to Heaven; and Heaven is the place of God's creating; where a commitment to love (to live, eternally, by love) is permanent...
Heavenly love is permanent - but love is alive, dynamic, changing (not static).
