This book is the sequel to "Truth on Tough Texts: Expositions of Challenging Scripture Passages" (also available on Amazon), a compilation of most of the articles that appeared in the first six years of the monthly publication, Truth on Tough Texts, launched by the author in August 2005. A few were omitted partly for space reasons but primarily because it was felt that a separate volume was in order to deal with the historical matters they address. Part I, Our Foundation, examines the value of studying Church History and then looks at the deep significance of the words of our Lord, "Upon this rock" (Matt. 16:16-19). Part II, The Five Solas of the Reformation, is the heart of the book in which we examine the core issues of the Reformation and are challenged with their importance for our day. Part III, Other History Lessons, addresses other historical figures and events that are also critical for our understanding in a day of growing indifference to these matters. There are also 60 illustrations, most of which were not in the original articles.
