Zipper us

The zipper:
Such a simple tool,
Yet, if it becomes inoperable
A garment cannot be worn,
A suitcase fails and its contents strewn everywhere,
Tent flaps cannot close and make it possible for creatures to enter.
Quite simply,
What was once useful
Becomes useless.

You, are the Zipper Slider
Connecting us,
Binding us,
Interlocking us
For a greater purpose, for a common goal.
Alone, we cannot function;
When you bring us together,
We are strong.

You, the Zipper Slider -
In bread and wine
In water and word
Bring us together,
one holy fabric.

[Other "z" words - there aren't many! Zap us! Zoom...?!]
