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.
Timothy KellerIf you come from insignificance and when you die you return to insignificance, then nothing is significant now.
Timothy KellerWhen we grasp that we are unworthy sinners saved by an infinitely costly grace, it destroys both our self-righteousn ess and our need to ridicule others.
