I don't know any Christians who take C.S. Lewis quite s literally.   

Tell us something please,

If when you had said

"(Y)ou could play any violin with any bow and cut as many keys as you wanted for any lock."


She had said "Yes but, you can't play a violin with a violin and you can't open a lock with another lock."

Or more to the point, "Let's see if your key fits."

Would you still be together?
