The purpose of affixing a Mezuzah is to fulfill a Mitzvah - a Divine Commandment. 

One of the purposes for this Mitzvah is to facilitate other Mitzvahs: As a Mitzvah hanging visibly on our doors the Mezuzah is a constant reminder that our homes and everything therein, belongs to  G-d, and must therefore be used properly.

The Mezuzah also serves as protection for the entire home. On every Mezuzah is inscribed G-d's name, "Shadai," which is an acronym for "Shomer Daltot Yisroel," the Guardian of the doors of Israel.

It is forbidden to erase or deface the name of G-d. It is therefore customary to insert a dash in middle of G-d's name, allowing us to erase or discard the paper it is written on if necessary.
