Mere Christianity (New York: HarperCollins, 1952)

“Now there are a good many things which would not be worth bothering about if I were going to live only seventy years, but which I had better bother about very seriously if I am going to live forever.”

“Every time you make a choice you are turning the central part of you, the part of you that chooses, into something a little different from what it was before . And taking your life as a whole, with all your innumerable choices , all your life long you are slowly turning this central thing either into a heavenly creature or into a hellish creature: either into a creature that is in harmony with God, and with other creatures , and with itself, or else into one that is in a state of war and hatred with God, and with its fellow-creatures, and with itself. To be the one kind of creature is heaven: that is , it is joy and peace and knowledge and power. To be the other means madness, horror, idiocy, rage, impotence, and eternal loneliness . Each of us at each moment is progressing to the one state or the other.”

Love Does: Discover a Secretly Incredible Life in an Ordinary World (Nashville: Thomas Nelson, 2012)

“Living a life fully engaged and full of whimsy and the kind of things that love does is something most people plan to do, but along the way they just kind of forget. Their dreams become one of those ‘we’ll go there next time’ deferrals. The sad thing is, for many there is no ‘next time’ because passing on the chance to cross over is an overall attitude toward life rather than a single decision. They need a change of attitude, not more opportunities.”

The Reason for God (New York: Penguin Group, 2008)

“A faith without some doubts is like a human body without any antibodies in it. People who blithely go through life too busy or indifferent to ask hard questions about why they believe as they do will find themselves defenseless against either the experience of tragedy or the probing questions of a smart skeptic. A person’s faith can collapse almost overnight if she has failed over the years to listen patiently to her own doubts, which should only be discarded after long reflection.

Believers should acknowledge and wrestle with doubts— not only their own but their friends’ and neighbors’. It is no longer sufficient to hold beliefs just because you inherited them. Only if you struggle long and hard with objections to your faith will you be able to provide grounds for your beliefs to skeptics , including yourself, that are plausible rather than ridiculous or offensive. And, just as important for our current situation, such a process will lead you, even after you come to a position of strong faith, to respect and understand those who doubt.”
