This book is the last of three on the miracles of Jesus and concentrates on the nature miracles. It's purpose is to place them in the context of our demand for signs and our scepticism about science and our appetite for ways of fixing the environment. Theologians used to have a respect for science and could understand God's ways through it. However, we now tend to take a very fundamentalist view of the Bible. The author shows that God gave his people a particularly good understanding of nature which we are in danger of losing in the secular 21st century.
