Anthology

"Time is infinite, it is limitless.
Time is elusive, it is cunning.
Time is questionable, it is a mystery.
Time can kill.
Time can save."
This book is an anthology series, of sorts. It consists of a selection of short literatures, each piece taking only one page. Some of the pieces are written as poems, some as paragraphs; each having a different writing style. The only consistency between them is that they only take up one page.
Can you work out the deeper meaning to each of them?
