Reza Aslan misrepresented himself on multiple TV shows as a Muslim who converted to Christianity when selling this book. He left out the small detail that he had converted back to Islam. However, he does provide an insightful look at the life of Jesus.
Although his purpose was to disprove the divinity of Christ, he inadvertently proved it. The eleven apostles who did not betray Jesus were all cowards on the day he was arrested. Yet, after his death, ten of them were tortured to death and refused to recant their statements that he had risen from the dead.
This is an extremely well researched and written book. I actually recommend it to anyone who is extremely acquainted with the New Testament, as you will see the flaws in his reasoning. To witness someone try so hard to tear down Christianity and fail is an experience I recommend.
