The Jollyblogger has an outstanding post on reading C.S. Lewis. Read it all.
David writes,
"What I find in Lewis is a confident faith which is not threatened by other religions or anti-religion. This is a refreshing alternative to fear-driven faith. "
That, in a nutshell, is the major contribution C.S. Lewis made to my life. He taught me that Christianity has nothing to fear from atheism. Though I never lost faith in Christ, my faith was a fear-driven faith in a number of ways. One of my fears was that Carl Sagan was right and that nihilism was ultimately true. ( note: Sagan was not a nihilist, but I would argue his worldview logically leads to nihilism ). I feared to look for the truth because of where it might lead. In Lewis, I found someone who had lived, read, and felt the full force of atheistic arguments and found them unthreatening. He did not dismiss the arguments of atheism like I think some Christians are prone to do today (e.g. fideists). Lewis took the arguments seriously and showed why they don't work.
Pastor Wayne, in his evaluation of Lewis, also makes a compelling point about friendship and plausibility structures. Plausibility structures are those group (or community) beliefs that define the realm of what is possibly true. Wayne writes,
Lewis was a committed atheist, but chinks in the armor came when several friends and others he respected either embraced the Christian faith or leaned in it's direction. These things perplexed Lewis, but it also seems that these friends and respected colleagues paved the way for him to (re)consider the Christian faith.
After interviewing a number of people for membership in our church this past Sunday, I was struck again by the role that friends play in shaping our ultimate beliefs. The obvious challenge before us as Christians is to not isolate ourselves from the world. We must be intentional about befriending those outside the church. Neglecting this hurts the church, and it also hurts our own growth and sanctification. That's right, I think my unchurched friends help me be a more compassionate Christian and less insular person. How many unchurched friends do you have? If the answer is none, how are you going to change that?
