Do you believe there is in fact a communication that God desires with individual humans? Yes, a communication in which I engage on a daily basis through prayer, meditation, and otherpractices.
Do you believe that the God Who can create this complex and so very delicately balanced Universe (an accident so rare as to be a 1 in 10120 possibility) is able to have His communication conveyed through this Bible which Ehrman denegrates as 'man-made'? Yes, and through all of the Scriptures of the world. The problem isn't God's message; it's that it was put together by human beings with agendas and they may not have been the clearest channels for God's message. In addition, many of them had agendas of their own that got superimposed on the message.
Whom do you suppose is served by this not so subtle insult to God's integrity as the 'Jesus Seminar' (which is Ehrman supported as I understand it) conveys? Well, I don't regard it as an insult to God. I regard it as investigation and research. If you're basing your faith on Jesus and teh evidence shows that Jesus may have been distorted (or any of God's messengers, for that matter), wouldn't you want to know that so you could follow his teachings more clearly?
You are in great peril with your self-made religiosity which rejects Jesus' own teaching. You appear on the surface to be comfortable with your creation.
If you ever conclude that Jesus meant what He taught when He stated on more than one occasion that He was the Way, the Truth, and the Light, that no man cometh unto the Father but by Him', if/when you come to that conclusion, you will be at the beginning of His invitation to you individually ... and perhaps your ears will no longer itch.
