Found at Sunlight of the Spirit:

If I Can Endure

If I can endure for this minute
whatever is happening to me
No matter how heavy my heart is
or how dark the moment might be...
If I can but keep on believing what
I know in my heart to be true,
That darkness will fade with morning
and that this will pass away, too...
Then nothing can ever disturb me
or fill me with uncertain fear,
For as sure as night brings dawning,
my morning is bound to appear...
