Introduction
How can the teachings of the Bible be packed into a small book like this? Consider that the entire Bible can be summarized in one word — “Christ.” Consider that its doctrines can be enclosed in the words — “Law and Gospel,” or the simple words (profound they they be) — “Sin and Grace.”
You will grow to appreciate the features of this book that make it so thoroughly Christian, so soundly Scriptural, and so characteristically Lutheran. It is filled with Bible verses; not just references, but verses printed out in their entirety. It is clear, for the Holy Scriptures are clear themselves. It is concise (brief), precise (exact), and incisive (penetrating) in its presentation. Its conciseness is the fruit of many years of faithful teaching in sermons, Bible Classes, confirmation classes (youth and adult), and seminar instruction. Its preciseness can be attributed to the painstaking study and labors so typical of its author. Its incisiveness has one cause only — the Word of God, the Sword of the Spirit, is a two-edged sword.
You will learn the reason that “theological” words such as “vicarious,” “objective and subjective,” and “imputation” are used, and how they alone express as accurately as possible the simple, yet deep, truths which they convey.
You are about to experience sitting at the feet of a great teacher as his only student, receiving through him, the saving truth that makes you free. I say, a great teacher, because he himself does not intrude upon the matters under discussion. The divine truth is laid before you in a straightforward and unbiased manner. It is instructive, convincing, and comforting, not because of the manner of presentation, but because of the matter that is presented. The manner is indeed pleasant, which adds to the attractiveness, appeal, and usefulness of this little book. Its contents are orthodox (correct-teaching), which is a commendation to the reader, a tribute to its author, and is satisfying fulfillment of a need felt by pastors and teachers who desire an instruction manual, and by maturing Christians who desire a book for review and comfort. May this little book be found and happily used to the fulfillment of that need, to the joy of many souls, and to the ultimate Glory of God.
