"You don't have to know a lot of things in order to make a huge difference for the Lord in the world. But you do need to know a few things that are great. And be willing to live for them and die for them." - John Piper
Paul writes in this passage of his desire for Christ to be honoured in his life and death, and then powerfully summarises how that is possible - "to me to live is Christ, and to die is gain".
