No God but One thoroughly evaluates several doctrinal and historical differences between Islam and Christianity to demonstrate Christianity’s truthfulness and the corresponding implications. Three primary themes flow throughout the book: Christianity and Islam are quite different; Christianity is historically sound, but Islam is not; and deciding between these two religions is a matter of life and death.
Nabeel Qureshi, a former Muslim turned Christian, is the author of No God but One, and he wrote this book specifically for those like himself who have wrestled to reconcile the claims of Islam and Christianity. He breaks his work into ten parts. In the first half of his book, Qureshi distinguishes the tenets of Islam from those of Christianity to confront the common assumption that these two major world religions are essentially similar (pg. 25). He boils Islamic doctrine of sharia law down to a solution for spiritual ignorance and the Christian gospel down to a redemptive relationship for sinners (pg. 44). The impersonal Allah of Islamic tawhid is distinguished from the personal trinitarian God of Christianity (pg. 69). He demonstrates the stark contrast between Islam’s self-seeking prophet Muhammad and Christianity’s self-sacrificial Savior Jesus (pg. 88). The Quran is shown to be Islam’s insufficient basis and the Bible to be God’s Word to his people for their study and guidance (pg. 111). The violent nature of Islam is contrasted with the peaceful nature of Christianity (pg. 147). Ultimately, Qureshi goes to great lengths to extrapolate the many differences between these two major religions.
