When David Livingstone began his trek across Africa in 1852, he carried 73 books which together weighed 180 pounds. After he had gone 300 miles he had to throw away some of the books because it was not feasible to carry so much through the jungle. He continued throwing books away as he went further into the jungle. Eventually his library had shrunk to one book—the Bible—this he did not throw away.
The Bible is truly the most important book in the world, yet many read it as if it were the least important.
