Did Jesus die on the cross for our sins as the Gospels describe? Or, as Muslims often contend, was Jesus rescued to heaven in order to avoid the shameful crucifixion that would be unbefitting of a messenger of God? This debate has raged for generations and has caused no shortage of frustration among those seeking to explain the central teaching of the Christian faith to those influenced by the Qur'an. What this book aims to do is uncover four barriers to understanding the biblical teaching on atonement that likely exist in the minds of our Muslim friends prior to asking about the historical reality of the Christ event. What we will discover is that the Qur'an diverges from the biblical teaching on atonement at the lexical, ritual, narrative, and worldview levels. Each of these points of divergence presents a barrier to communication. Therefore, before arguing with our Muslim friends that Jesus died on the cross, we must provide an answer to the prior question, why would it matter? This book argues that the Letter to the Hebrews provides a particularly helpful biblical starting point for overcoming all four barriers.
