If you do not believe
Then your life will have no meaning,
You will live your days in darkness
Unable to find your way.

You will bear the burden of your suffering alone
Without the comfort of a friend or loved one,
And nobody shall see the tears that you weep.

But if you do believe,
Then the way shall be clear,
For the light that burns within you
Shall be revealed unto all.
