One of the most famous examples being C.S. Lewis himself, his book A Grief Observed (written after his wife passed) being one of the most clear examples of it. On a slightly related note, there's an excellent film adaptation about C.S. Lewis's relationship with his wife called Shadowlands, starring Anthony Hopkins. Amazing that the man who played Hannibal Lecter could also portray the most famous Christian thinker of the 20th century so well.
I'll second that recommendation. Shadowlands is a superb film. It's very much worth watching even if you have little sympathy with Lewis's religious views.
