Here are 3 quotes by Tim Keller, pastor of Redeemer Presbyterian Church in NYC. He has authored many books including The Prodigal God and Counterfeit Gods.
“A faith without some doubts is like a human body with no antibodies 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.”
“The gospel is this: We are more sinful and flawed in ourselves than we ever dared believe, yet at the very same time we are more loved and accepted in Jesus Christ than we ever dared hope.”
“If we are saved by grace alone, this salvation is a constant source of amazed delight. Nothing is mundane or matter-of-fact about our lives. It is a miracle we are Christians, and the gospel, which creates bold humility, should give us a far deeper sense of humor and joy. We don’t take ourselves seriously, and we are full of hope for the world.”
