Guten-Something...
A book collector ran into an unbookish acquaintance who soon revealed that old books didn't mean anything to him. In fact, he observed he had just thrown away a big old Bible which had been packed away in the attic of his ancestral home for generations. He was describing it and said, "Somebody named Guten-something had printed it."
The bibliophile gasped. "Not Gutenberg! You idiot! You've just thrown away one of the first books ever printed. A copy sold recently at an auction for over a million dollars!" But the other man was unmoved. He responded, "No, not my copy. It wouldn't have brought a dime. Some fellow named Martin Luther had scribbled notes all through it!"
He didn't see what he had seen. That seems to be a characteristic of humanity, especially with regard to the revelation of God in nature, in the Bible, in the testimony of others, and particularly in the life of Jesus.
