Throughout Church history, a lack of clear thought has been the chief cause of heresy: wherever indifference to doctrine and theology has arisen, neglect and rejection have soon followed. Christianity today faces a crisis in thinking: there is both an indifference toward, and neglect of, serious thought about Christian doctrine and theology. Instead, personal experience has been given primacy. Thinking Christianity attempts to reverse this popular attitude and forestall the rejection of the Christian gospel that will otherwise inevitably follow. Author Daniel Klassen covers two aspects of thinking in the Christian faith: the necessity for thinking, and the need for proper thinking. Throughout the book, he attempts to answer these questions with clarity and truthfulness by expounding Scripture, using historical examples from the Reformation, and exploring philosophical ideas. This clearly reasoned, timely book will help Christians live in assurance and confidence in God—and preserve the gospel for future generations.
