If we study history we can find that historians provide the who, what, when, where, and how, but only the Bible can provide the why. It is a tool, a manual for living our lives here on earth. It is history, because history repeats itself, it offers us a chance to learn from others that have passed through and delt with things we must face today. It offers us advise on how God wants us to live our lives, and use the bible to guide our paths.
Psalms 119: 1 [a] Blessed are they whose ways are blameless,who walk according to the law of the LORD.
2 Blessed are they who keep his statutes
and seek him with all their heart.
3 They do nothing wrong; they walk in his ways.
But it is also as mentioned earlier by one of your readers; if we have accepted Christ as our savior then he dwells with in us and leads us on the path to righteousness and there fore offer us guidance and assistance if we are open to his will. But I might caution you with regards to other books and written artifacts as tools to guide our lives by quoting the final verses of the New Testament:
Rev 22 18) I testify to everyone who hears the words of the prophecy of this book: if anyone adds them, God will add to him the plagues which are written in this book;
19and if anyone takes away from the words of the book of this prophecy, God will take away his part from (the tree of life and from the holy city, which are written in this book.
