"lest anyone think this isn't something marvelous, we'd like to give you this challenge. Find ten people from your local area having similar backgrounds, who speak the same language, and all are from basically the same culture. Then separate them and ask them to write their opinion on only one controversial subject, such as the meaning of life.
When they have finished, compare the conclusions of these ten writers. Do they agree with each other? Of course not. But the Bible did not consist of merely ten authors, but forty. It was not written in one generation, but over a period of 1,500 years; not by authors with the same education, culture and language, but with vastly different education, many different cultures, from three continents and three different languages, and finally not just one subject but hundreds."
read the Bible and you'll see what they mean.
That's a good one.
