I Remember Two Things from Religion Class

Our fifth grade text book for religion class had a poem in it that I remember. I guess you'd call it a poem. It said: 

I believe in the sun even when it is not shining.

I believe in love when I feel it not. 

I believe in God even when He is silent. 

                                                       *

It said it was found on the wall of a Nazi prison camp. That, and the story of Moses crossing the desert are the only things I really remember from religion classes, and I went to Catholic grade school and Catholic high school until the middle of junior year. That's a lot of years of regular religion classes without a lot to show for it. What did we talk about all those years? I have no idea.
