Each to his own. I am not likely to take guidance from anyone who is a frequent guest on Larry King Live and I saw nothing on this mans Internet site that would lead me to believe he is anything but a small minded man whose hubris leads him to far overestimate his own wisdom and knowledge.
You obviously do not know John MacArthur. He is without a doubt one of the finest Bible teachers alive today. Your estimate of him is woefully lacking. You say you looked at his web site. Did you look at any of the sermons he has preached over the last 40 years?
You might want to check out this one sermon called A Nation Abandoned By God. There is no hubris in this man at all!
BTW - what qualifies you to determine that he is a "small minded man whose hubris leads him to far overestimate his own wisdom and knowledge" ??
