A feeling of anger

The anger inside me
seems to be an ever burning fire.
God fearing friends assure me,
"God has a plan".
That every wrong and painful thing to happen,
has a "reason".
That I should trust the almighty,
the one that deems himself fit,
to trial and test my life,
like a rat in a cage
and the world his laboratory.
And I, the unfortunate rat
never to know the reasons
behind the masters act.
