Many people assume that the Bible's writers were also its authors.  That is true for most of the books on library shelves; and those editors who compile or condense another author's work will also want to express some personal interpretation.  But the Bible is radically different.  None of its 40 writers were its original author. The authority behind everything they wrote was God's Holy Spirit.  He breathed God's truth into their minds and hearts, enabling them to write things they did not understand, and even accurately predict the future.
 
So the authorship was God's, even though the text and grammatical style was in the writers' hands.  But, they did not invent the ideas, nor did they set out to be world famous authors.  They simply allowed God to use them.  Neither did they select themselves for the job: God chose them.  Neither did they even fully understand what they were writing, but they knew it was true and that God would explain it one day (1 Peter 1:10-12)

Nor did they use the opportunity to express their personal views: the Holy Spirit guided them to express the message God gave them in a way that would communicate to their immediate audience, and also to us many centuries later.  Because He is the author, He can also explain it to our hearts in such a way that we understand what He is saying to us and that it bears His authoritative gravity.
 
All those who seek the Lord, and His will, need to understand this about the Holy Scriptures. If we assume that the Bible's words are human inventions, then we will judge them by our standards.  But if we appreciate that God Himself is speaking to us, then we will (or should) be seriously in awe of what we read.  Every instruction is to be obeyed, every promise is to be trusted; every rebuke should stimulate repentance, and every warning heeded immediately (2 Timothy 3:15-16).  In other words, the Word of God is not just good advice or a collection of suggestions to be considered, but Royal commands to be put into action (2 Peter 1:19).  So, expect God to speak when you read the Bible, and when He does, do it!
