This week in our series Make Me a Theologian we are laying the top of the sandwich down for the final chapters of Mere Christianity. What is the Trinity and how can God beget God? What do we as humans have to do with the God who stands outside of time? C.S. Lewis goes on to highlight the cost of our faith. Do we consider Christianity to be a hard or an easy life? And what is the purpose of becoming Christian? It sometimes feels too hard to explain why someone might need Jesus when their life is already so good. Is there more to Christianity than simply making us into 'nice, moral people'?
