I especially love this quote by one of my top HEROES (!!) Eric Liddell. He wrote this in a booklet for the Chinese Christians whom he worked with, before Japan took over China and sent him to a prison camp called Weihsein, where he died. It is one of my favorite quotes.
"Victory over all the circumstances comes not by might, nor by power, but by a practical confidence in God and by allowing His Spirit to dwell in our hearts and control our actions and emotions. Learn in these days of ease and comfort so that when the days of hardship come, you will be fully equipped to meet them."
