To create an analogy: Imagine if 2000 years from now, there was more documentation on the life of a traveling minister (whose ministry lasted three and a half years) than there was for the President of the United States, during whose term the preacher preached.
Furthermore, Dr. Habermas once told me, “Actually, the life of Jesus is recorded in whole or in part, different segments, in about 20 different non-Christian sources, archaeological or historical, outside the New Testament.”
He went on to say, “Now most of these are little snippets, a sentence here, a paragraph there, but you put them all together and there’s approximately 60 to 65 facts concerning the life, death, resurrection, teachings of Jesus in the earliest Church. You can get an outline of his life and never touch the New Testament.”
So the next time somebody tries to sell you on the idea that Jesus cannot be documented in history---even secular history, please lovingly but firmly stop them in their tracks…with the facts.
No reputable historian denies the historicity of Jesus.
