In this book the author shows evidence of the Christian doctrines of the Trinity, justification, regeneration, and other dogmas of the Christian faith from the Quran. He documents extensively showing what ancient Christians believed and points out ancient Christian heresies that are condemned by the Quran. He uses principles derived from the Quran to interpret the Quran. The author takes a moderate view of the Quran. He neither accepts it as canonical Christian Scripture nor bashes it as so many non-Muslims do. He shows some of the previous sources from which much of the Quran is derived - sources such as the Talmud, rabbinical commentary, apocryphal Christian writings, and the canonical Scriptures of Christians. (18th and 19th century non-Muslim scholars were aware of the sources from which much of the Quran was derived.) He even points out that passages in the Bible were derived from non-canonical sources. In this book he talks about the purpose of God's creation and the blessings that await believers in the afterlife. He deals with some of the Quranic verses that have sparked controversy among Christians and Muslims, such as, the "Sword Verse," the "Wife-beating Verse," and the "Pedophile Verse." He talks about what the Quran says about the Bible. He points out passages in the Old Testament that the Masoretes altered and provides proof that those passages were altered. As for the Quran, he points out that even it is not exempt from being altered. He still maintains respect for both the Bible and the Quran. He maintains that we might get to see the perfect copies of these sacred books after the Second Coming of Jesus Christ.
