“A faith without some doubts is like a human body with no antobodies in it. People who blithely go through life too busy or indifferent to ask the 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 failed over the years to listen patiently to her own doubts, which should only be discarded after long reflection.”
― Tim Keller

“If you believe what you like in the Gospel, and reject what you don't like, it is not the Gospel you believe, but yourself.”
― Augustine

“The man who cannot listen to an argument which opposes his views either has a weak position or is a weak defender of it. No opinion that cannot stand discussion or criticism is worth holding. And it has been wisely said that the man who knows only half of any question is worse off than the man who knows nothing of it. He is not only one sided, but his partisanship soon turns him into an intolerant and a fanatic. In general it is true that nothing which cannot stand up under discussion and criticism is worth defending.”
― James E. Talmage
