C.S. Lewis, one of the foremost writers of the last 100 years, has written on a variety of topics including children's stories, Christian apologetics and pain and suffering. One of his best books speaks to the notion of being a Christian, and it is called Mere Christianity.
In his book Mere Christianity, C.S. Lewis seeks to dispel some of the difficult thoughts and processes that a Christian can do, and to really look at the faith as a new and fresh idea apart from dogmatic laws and regulations. As an incredible thinker, C.S. Lewis offers those people who feel they are "too smart" or "too advanced" to follow Christ. His insights have helped many including myself see that Christianity is not for the slow or non-intelligent but for everyone.
I recommend this book for anyone, and would hope that you would pick it up and give it a try!
