Can We Trust the Gospels? Investigating the Reliability of Matthew, Mark, Luke, and John by Mark D Roberts and published by Crossway Books.
Are the Gospels simply two-thousand-year-old partial manuscripts penned many years after the original incidents or God's inspired Word preserved by the Spirit and delivered to us through the blood of the faithful? Mark Roberts turns his weblog series on the trustworthiness of the Gospels into book form, and he addresses these issues and more in Can We Trust the Gospels?
Digging deep to uncover the sources that the evangelists used, perceived contradictions within the four books and the reason for there being four of them (and why these particular four), Roberts presents a full treatise on the Gospels and their place within theology and Christendom.
