The Bible was written over a period of 1,500 years and by 40 authors. It tells one story about the Messiah, God’s Son, beginning in Genesis, the first book, to the end. These men could not consult with each other because of the many years that separated them; yet the Bible remains harmonious and has no contradictions. Some of the authors of the Bible were kings, fishermen, a tax collector, shepherds, prophets, and a physician.
The 66 books of the Bible tell us about many things including why we are on the earth; what God is like; and God's plan of salvation. Does it make you wonder how a book could be written over so many years and by so many men and still be cohesive?
God gives us the answer in the Bible. God is the real author of the Bible because He inspired these men to write His Book.
