"The Bible, which consists of 66 books, was written over a period of 1,600 years by 40 different authors, but it speaks with one voice and has one main message, and that is the message of redemption from sin through Jesus Christ. The Old Testament portion of the Bible, consisting of its first 39 books, points to the coming of Jesus and prepares the way for His coming through types and prophecies. The New Testament portion of the Bible, consisting of its final 27 books, describes how that Jesus, the eternal Son of God, the Creator, came into this world through the womb of a virgin, lived a sinless life, and suffered and died on the cross to redeem man from his fallen condition. Jesus died, was buried, and rose from the dead the third day. He then instructed His followers to go into all the world and preach the gospel of redemption. Those who believe are forgiven of their sin, are brought back into relationship with God, and are given eternal life. The main theme of the Bible is stated in a nutshell in John 3:16: "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.""

"Forty independent writers were used in its compilation. They wrote over a 1,500 year time span. They lived in three different continents: Asia, Africa and Europe. Moses wrote in the desert of Sinai, Paul wrote in a prison in Rome, Daniel from exile in Babylon, and Ezra in the ruined city of Jerusalem. They spoke and wrote in three different languages. They had twenty different occupations, which included a couple of kings, a general, at least two fishermen, a musician, a priest, a tax collector, a physician, etc. It has a cast of 2,930 characters in 1,551 places. It covers a huge number of different subjects. Isaiah wrote to warn Israel of God's coming judgment on their sin, Matthew wrote to prove to the Jews that Jesus is the Messiah, Zechariah wrote to encourage a disheartened Israel who had returned from Babylonian exile, and Paul wrote addressing problems in different Asian and European churches.
"It was written under many different circumstances. David wrote during a time of war, Jeremiah wrote at the sorrowful time of Israel's downfall, Peter wrote while Israel was under Roman domination, and Joshua wrote while invading the land of Canaan. Its message is expressed in all literary forms (poetry, prose, etc.). Yet without possible concert or collusion, they produced a book which, in all its parts, is pervaded by one spirit, one doctrine, one design, and by an air of sublime authority which is its peculiar characteristic. It is amazing that with such diversity, there is such unity in the Bible. That unity is organized around one theme: God's redemption of man and all of creation. Hundreds of controversial subjects are addressed and yet the writers do not contradict each other."

The writings cover a variety of literary forms: history, law, prophecy, poetry, parable, allegory, biography, memoir, personal correspondence, and apocalyptic."
