I believe in the sun even when it isn't shining.
I believe in love even when I am alone.
I believe in God even when He is silent.
(Graffiti found in 1945 on the wall of a basement in Koln, Germany, where a Jewish believer is thought to have been hiding from the Gestapo.)
This was printed on the first page of a new book I just got called 'God on Mute: Engaging the Silence of Unanswered Prayer'. Can't wait to get into it.
