We keep Nelson Mandela in our thoughts and prayers this week as he battles declining health. Here are some of his timeless quotes:

“Education is the most powerful weapon which you can use to change the world.”

“A good head and a good heart are always a formidable combination.”

“For to be free is not merely to cast off one’s chains, but to live in a way that respects and enhances the freedom of others.”

“There is no passion to be found playing small – in settling for a life that is less than the one you are capable of living.”

“It always seems impossible until it’s done.”

“There can be no keener revelation of a society’s soul than the way in which it treats its children.”
