“If I find in myself desires which nothing in this world can satisfy, the only logical explanation is that I was made for another world.”
― C.S. Lewis, Mere Christianity

“Why is it that some Christians cross land and sea, continents and cultures, as missionaries? What on earth impels them? It is not in order to commend a civilization, an institution or an ideology, but rather a person, Jesus Christ, whom they believe to be unique. ”
― John Stott

“The spirit of Christ is the spirit of missions. The nearer we get to Him, the more intensely missionary we become.”
― Henry Martyn

“I am wired by nature to love the same toys that the world loves. I start to fit in. I start to love what others love. I start to call earth "home." Before you know it, I am calling luxeries "needs" and using my money just the way unbelievers do. I begin to forget the war. I don't think much about people perishing. Missions and unreached people drop out of my mind. I stop dreaming about the triumphs of grace. I sink into a secular mind-set that looks first to what man can do, not what God can do. It is a terrible sickness. And I thank God for those who have forced me again and again toward a wartime mind-set.”
― John Piper, Don't Waste Your Life
