The Gospel of Barnabas is widely considered a pseudepigraphal work, likely written no earlier than the late medieval period. It should not be confused with the Epistle of Barnabas or other ancient Christian texts whose origins and manuscripts are well established.

This book is about how to present the Gospel of Jesus Christ to Muslims. Over the span of many years, I noted that most people asked more questions about presenting the Gospel to Muslims than any other topic. They indicated to me that it was not an easy task. I have come to believe that their greatest need was not presenting a book of stories, testimonies, and example of dialog with Muslims. Their greatest need is to clarify the biblical foundations the Gospel and for the methodologies of presenting it to Muslims. I can summarize every meaningful discussion I had with others about the Gospel and Muslims and it ultimately centered around these biblical and theological foundations that are shared in this book.
