Why did they write The Bible?

Answer 1

According to The Bible, its writers were "inspired by God's Holy Spirit" to do so.

"All scripture is given by inspiration of God..." (II Tim.3:16).

The reason they were so inspired is for man's instruction for achieving "perfection."

The Bible, according to the Bible: "...is profitable for doctrine, for reproof, for correction, for instruction in righteousness: that the man of God may be (or become) perfect, throughly (thoroughly) furnished unto all good works." (verses 16-17)

"...the LORD said unto Moses, 'Write this for a memorial in a book..." (Ex.17:14 KJV).

"...'Write thou these Words...'" (Ex.34:27 KJV).

"Thus speaketh the LORD God of Israel, saying, 'Write thee all these words that I have spoken unto thee in a book." (Jer.30:2 KJV)

"...Write the vision, and make it plain upon tables..." (Hab.2:2 KJV).

"...'We have found Him, of whom Moses in the Law, and the prophets, did write, Jesus of Nazareth, the son of Joseph.'" (John 1:45 KJV)

"I write not these things to shame you, but as my beloved sons I warn you." (I Cor.4:14 KJV)

"...'the things that I write unto you are the Commandments of the LORD.'" (I Cor.14:37 KJV)

"...'I AM Alpha and Omega, the First and the Last: and, What thou seest, write in a book...'" (Rev.1:11 KJV)

"...'WRITE: for these Words are True and Faithful.'" (Rev.21:5 KJV)
A number of different religious traditions have writings regarded as sacred Scripture. These writings provide authoritative guidance, allowing believers to have confidence as they follow the rules and practices of their faith. Narrative stories in Scriptures provide common histories for communities of faith, and act as foundations for faith identity and models for practice.

In many cases, members of the religion believe that their Scriptures have been given directly from their Deity, through inspiration or other miraculous means. Adherents will insist that their Scripture was not written or made by any human agency but is a miraculous gift from their god. Fundamentalist Christians, and Evangelical Christians to a lesser extant, take this position.

Answer 2

Yair Zakovitch, Dean of Humanities at Hebrew University is quoted as saying, "The thing to remember about the Bible is that the events and characters are just vehicles to convey messages. The biblical narrative was written to educate our young nation, not so much to tell us what really happened." Zakovitch speaks for the Hebrew Bible, or Old Testament, but a similar explanation can be put forward for the New Testament.
