Writing is the means though when speech can be transmitted and preserved.

For many years the real and truth Word can be preserved, but the languages change, people speech change and cultural aspects could also change the context of the Words we want to transmit and preserve.
Writing has been a very important and useful tool for man, when writing for example things as simple as a description; we are not only saying some facts but we are drawing a complete scene in which we can make the readers see everything we want them to see in the way we want them to look at it.
Writing is communicating.
We can tell someone near what our ideas are, but when we write we can say our ideas in such a way that everybody even people far away from us can be informed in any place at any time.
The bible is one example of the successful of writing, the way each word has been preserved taking into account the development of the languages and the translation from one language to another ; the main purpose of the context has been preserved and transmitted till today’s day.
