In early 2016 I found myself laying in a hospital bed at the Royal Marsden in Fulham, diagnosed with terminal cancer, I decided to write about my faith in Christ; what it is and how it has been shaped and tested by a life that is lived out in the unpredictability of a world that can be so harsh and cruel. My starting point is to examine what sin is and what it does, paving the way for me to explain the necessity of salvation and what it does. I have made this my starting point because this is where faith begins. The fundamental message of the book is to acknowledge that, as a Christian, life can be filled with extreme pain, confusion and disillusionment and begs for meaningful answers to some very serious questions. The book takes an honest look at faith under the examination of someone who has experienced the safety of Christianity from childhood, yet along the way became one of the biggest sceptics of the Christianity that I saw around me. It was a scepticism that led me to the point of considering abandoning whatever faith I thought I had. This is a dilemma that I know a lot of Christians are tempted by and I hope that this book will give to them the encouragement, support and determination to press on. In this matter I attempt to examine what genuine faith is and what it is not, what it will do and what it will not do. I seek to highlight that the person with genuine faith must expect and be prepared for their faith to be tried and tested by God Himself and what His purpose in doing so is. The conclusion that the book as a whole alludes to, is that whilst there are times when faith does not seem to work, the faithfulness of what God has accomplished through Jesus Christ determines that faith always works.
