A prayer of John Henry Cardinal Newman...

God created me
to do him some definite service;
he has committed some work to me
which he has not committed to another.

I have my mission -
I may never know it in this life,
but I shall be told it in the next...
Therefore, I will trust him...
If I am in sickness,
my sickness may serve him;
in perplexity,
my perplexity may serve him;
if I am in sorrow,
my sorrow may serve him...
He does nothing in vain;
he may prolong my life,
he may shorten it,
he knows what he is about.
