As its title implies, this book is the outcome of a lifelong application of Ecclesiastes 12:1. It is not primarily about the science versus the Bible debate but about the more important matter of what the Bible, the Word of God, teaches about creation; and the need for 21st-century Christians to stand for this teaching in an increasingly materialistic and secular world, marked by aggressive and hostile atheism. Science, at its best, is only relative truth for today and may be proved wrong tomorrow; but Scripture is absolute truth which abides forever. As a teenager the author experienced the penetrating effect of God’s Word and after a career of over forty years as a practising industrial chemist he remains as convinced as ever of the accuracy and inerrancy of the Bible. As the uniquely reliable source of truth about all matters of the Christian faith, it should be no surprise that it clearly addresses the issues relating to the origins of the universe, the world and life itself. Indeed, creation is a bedrock under the whole of Bible truth. To deny, question, or even modify, the Genesis account is to challenge the truth of God. It’s by faith that Christians understand that the universe was created by the word of God. So what must I believe about creation? This apologia for the biblical view attempts to answer that crucial question.
