My favorite book of all time is Mere Christianity by C.S. Lewis. When I first became a christian, I decided to undertake the great feat of converting my entire family to christianity. While I now realize this mission is not my job and I am not the second coming of Christ, I have learned a lot in the process. In Mere Christianity, Lewis builds the validity of Christianity from the ground up. He dives into the nature of humanity and religious doctrine and then begins to combat atheism. I had never read a case for christianity that builds points so carefully, proven meticulously one by one, with no given facts as a premise. Lewis says, “If you are a Christian, you are free to think that all those religions, even the queerest ones, contain at least some hint of the truth… where Christianity differs from other religions, Christianity is right and they are wrong. As in arithmetic -- there is only one right answer to a sum, and all other answers are wrong; but some of the wrong answers are much nearer being right than others.” The idea of salvation only coming from Christ is one that has always been very challenging for my family and many of my friends. Coming to terms with the fact that people you have lost that were not christian may not be in heaven is hard to swallow but it is something that continues to push those who hope all roads lead to the same place to question the likelihood of their beliefs. It pushes them to reevaluate what they believe as their truth and its validity. Where one school of thought may have coherent pillars, not in contradiction to each other, another may correspond with the questions you have about humanity and the idea of god. However, christianity is the only set of beliefs that both corresponds with the questions of humanity and coheres so that none of its truths contradict another. While I have learned that in conversation, you don’t need to bombard someone with facts to win them over(the gospel is convicting enough), I have also found that the defensibility of christianity is very important for those who are held back by logical doubt. Learning about God and the validity of christiainity has brought me a lot closer to Him, and I hope to help other people experience this, too.
