The Bible - the Book of Moral Stories?

It is clear many - Christians and others alike - hold the folks whose stories are told in the Bible to a high, almost divine, standard. Because of this, when some individuals are challenged about their behaviour, they come back with 'But David in the bible did this', 'Abraham did this in the bible'. Alternatively, others have expressed their disappointment in God for allowing His chosen ones conduct some wrong behavior or the other in the Biblical times. And this has become a source of confusion. 

The conception that the Bible is a collection of moral stories about good men and women whose examples we should follow is wrong. That is not the message of the Bible, and that was not the purpose it was written for. The Bible's main objective is revealing the plan of a good God to redeem sinful humankind through the finished work of His son, Jesus Christ. And in accomplishing this plan, God used humans - both righteous and unrighteous ones. If God had to wait around for people to meet His perfect standards before He could use them, it is highly unlikely the salvation plan would have taken off. 

God has not raised any of the Bible characters as shining moral models: the only model He has approved of is Christ. “This is my Beloved Son, in whom I am well pleased.” 

Of course, this raises a question: if this was the case, why was so much detail provided on the lives of these characters in the scriptures? I would say it is to buttress the point, that the Bible is NOT the Book of Moral Stories. If the Bible only recorded the good sides of those people and not the bad, we would exalt and idolize them for the ways they were mightily used of God. But God’s priority is that we are grounded in right knowledge and truth, even if we feel disappointed by the facts.
