Some quotes from The Reason for God by Timothy Keller:
Sometimes people approach me and say, “I really struggle with this aspect of Christian teaching. I like this part of Christian belief, but I don’t think I can accept that part.” I usually respond: “If Jesus rose from the dead, then you have to accept all he said; if he didn’t rise from the dead, then why worry about any of what he said? The issue on which everything hangs is not whether or not you like his teaching but whether or not he rose from the dead.” […] we can’t live our lives any way we want. It also meant we don’t have to be afraid of anything, not Roman swords, not cancer, nothing. If Jesus rose from the dead, it changes everything.
Each year at Easter I get to preach on the Resurrection. In my sermon I always say to my skeptical, secular friends that, even if they can’t believe in the resurrection, they should want it to be true. Most of them care deeply about justice for the poor, alleviating hunger and disease, and caring for the environment. Yet many of them believe that the material world was caused by accident and that the world and everything in it will eventually simply burn up in the death of the sun. They find it discouraging that so few people care about justice without realizing that their own worldview undermines any motivation to make the world a better place. Why sacrifice for the needs of others if in the end nothing we do will make any difference? If the resurrection of Jesus happened, however, that means there’s infinite hope and reason to pour ourselves out for the needs of the world.
Christ is risen! He is risen indeed!
