One of my favourite phrases is “This too shall come to pass”. It is one of the phrases that console me and challenge too, since if something very good is happening then I need to enjoy it in full knowing it will come to pass. On the other hand if going through difficult periods am happy to know if it will be forever. I sought to look at the history behind the phrase and the most common one is this story.  (http://pravstalk.com/this-too-shall-pass)
