How would you translate this expresion and where does it's meaning comes from? I just can't imagine it.

"Every cloud has a silver lining."

Thanks.

No hay mal que por bien no venga
The origin of the phrase is traced to John Milton (http://en.wikipedia.org/wiki/John_Milton)'s 'Comus (http://en.wikipedia.org/wiki/Comus_%28John_Milton%29)' (1634) with the lines,
“ Was I deceiv'd, or did a sable cloud
Turn forth her silver lining on the night?[3] (http://en.wikipedia.org/wiki/Silver_lining#cite_note-2)
”
