"People talk of the sacrifices I have made in spending so much of my life in Africa.
Can that be called a sacrifice which simply pays back a small part of the great debt we owe God?
Is anything a sacrifice when it brings its own blessed reward in a healthful activity, consciousness of doing good, peace of mind, and a bright hope of a glorious destiny?
Away with such a thought.
It's not sacrifice- it's a privilege."
