The Bible makes the claim to absolute truthfulness and infallibility. It then provides the internal evidence to verify this claim. Complete harmony through sixty-six books by about forty different writers, spanning one and a half millennia, would be impossible if the author were not the Holy Spirit. In order for Scripture to make the claim of truthfulness, it must also contain the promise of preservation. God's promise to preserve his pure Word is dramatically fulfilled in the 1611 publication of the Authorized Version of the Bible, more commonly known today as the King James Version. The Bible's power, feared by its enemies, is the power to transform those who submit to its claims, and love its precepts. The written words of the King James translators have had a greater influence on this world than any other literary work the planet has ever seen. They have changed the course of nations, and altered history in a way the translators could not have fathomed. They have transmitted the precious gospel message to more souls than all other agencies combined. Only in eternity will their power be comprehended. The King James translators of the Bible achieved what has never been accomplished before, or since. Although the translators are mostly unknown, and their masterpiece is either unappreciated or maligned; though the importance of their accomplishment is not comprehended; though every power of hell and demons has been arrayed against this book, yet their legacy survives as the living Word of God - the best selling book of all time. Though God promised to preserve his word, the stern facts of history and the unyielding testimony of Scripture prove that attempts have been made to pervert God's Word: "ye have perverted the words of the living God," Jeremiah 23:36. Compare: KJV Job 19:26 "yet in my flesh shall I see God: " ASV Job 19:26 "then without my flesh shall I see God;" Simple logic demands that two opposite statements cannot both be true. Therefore one must be false. The one that is false cannot be God's pure, true, unperverted Word. Thus, to fulfill the promise of preservation, the Scripture must contain a way to distinguish the genuine from the counterfeit. With demonstrable and rather serious differences in so many current versions of the Bible, how can we be certain what is God's true and preserved Word? This book answers this question.
