“Once you have accepted Christianity, then some of its main doctrines should be deliberately held before you mind every day. That is why daily praying, and Scripture reading and church going are necessary parts of the Christian life. We have to be continually reminded of what we believe. Neither this belief nor any other will automatically remain alive in the mind. It must be fed…if you examined one hundred people who had lost their faith in Christianity I wonder how many of them would turn out to have been reasoned out of it by honest argument? Do not most people simply drift away?” C S Lewis, Mere Christianity
