From the YouTube description: In this lecture, entitled External Evidences for the Truth of the Gospels, Dr. Timothy McGrew maps out the external and internal evidence bearing on the authenticity of the Gospels and explores some of the positive external evidence for their truthfulness. These include non-Christian sources and incidental historical confirmations. This is one hour of content followed by thirty minutes of Q&A.
