JLM - I don't think anyone can afford you "iron clad proof". There are historical and archeological evidences that support/determine that Jesus did exist. That is to say, yes, Jesus was here on earth some 2000 years ago. If question whether or not Jesus lived, then we should also question if Julius Ceasar and his contemporaries lived. In other words, how much do you trust history? I do not think you would find many a historian, archeologist, or theologian (from any religion) that would deny that Jesus was a historical figure. I'm not saying that people can't be of the opinion that he did not live, but to believe that Jesus did not exist runs against much common and accepted knowledge based on fact.I think before we can go anywhere with this discussion, we have to determine, what all the facts are about Jesus beyond any doubt. Was there really such a man? Did he actually do all the things attributed to him? Is there any iron clad proof that he did even one of the things attributed to him? If we can't verify these "facts", then any discussion could be based on false premises.
From there, "You've gotta ask yourself a question: "Do I feel lucky?" Well, do ya, punk?" Yeah, don't ask me why I went for Eastwood's Dirty Harry line. I suppose I should have quoted scripture. Anyway, Do you believe Jesus lived and more importantly, do you believe he was God? In my opinion, that is the most important question of a person's life. Because the answer is life altering.
