Breaking Up With God

We have a student art exhibit in the college gallery. There are lots of paintings, prints, sculptures, hangings, etc. In the center is this exhibit on a table that I find intriguing. It's a painted umbrella, hand, pen on a board that says:

Dear God,
This isn't working for me.
I just can't trust you anymore.
Thanks,
Chris

It sounds just like a break-up letter to me.
