Why is it what is visible is temporary and what is invisible lasts forever?

[Counterclocking]

I want a good answer. I don’t want answers like these: (Because the Bible says so, Because it is, etc.)

I want to know why it is in life and/or why life’s made that way.

The things that are visible to humans in this life are here for just a moment and then gone. Paul, the author of the text, describes them as transient. This is true in two senses. Obviously, anything that exists in this world lasts a very short time in comparison with those things that last forever. Secondly, though, human lives are far shorter, yet, when compared to human history. What is visible to us will come and go very quickly. The invisible God, though, is "eternal," meaning "outside of time." Whatever exists with Him in the spiritual world will never end.
Christians, myself included, believe in a glory that exists after death, Heaven and eternity spent with God. So we focus our hopes on that, rather than allow ourselves to be weighed down by the momentary struggles of life.

What makes you think that's the case? The weather is governed (well, part of it) largely by the interactions of cold air masses and warm air masses, both of which are invisible, and neither of which last forever. Meanwhile, you've got horseshoe crabs, fruitcakes, and Dick Van Dyke (all of which originated at about the same time), which are clearly visible, and have lasted for a good chunk of forever so far.

kuz if you SEE it , it reflects light so it is matter which crumbles.

but a soul does not reflect light so not physical can't see nor crumble decay.
