Who lit that firework?

A single firework burst in the beginning,
Through and around us its showers shine,
From ages ago, until the end of time.

Who lit that firework, nobody knows.
Shocked He must be, just as anyone would,
If the sparks of our fireworks could speak.

Aren't we the happiest, when the black night sky,
Is peppered with sparks that shine ever so brilliantly?
What must be the purpose of our life then?

Dare I say, it must be to shine in the darkest hours,
And just as we are saddened by the fading sparks,
So must be He, at our fleeting existence.

But, however short it may be,
The smiles it brings, the memories created,
Must be etched forever in His mind.

If all we need to do is shine brilliantly,
If all we need to do is shine beautifully,
Then, does it matter who lit that firework?
