I would dispute this.
How many other books do you read apart from the Bible? If you do, of what benefit are they to you?
Text books certainly make a person clever and teaches truths about the world, otherwise we wouldn't be able to apply what they teach in life.
Since there have been books and stories that speak out against murder and lying and how to love others, there are certainly books that approve of certain righteousness in the bible.
Accounting books are some of them.
I had to because it is my profession to be an Accounting instructor.
I teach Accountancy to junior and senior college students.
But just as I said, Accounting books cannot make me, my students or anybody wise in the knowledge and faith in Jesus Christ for us to be saved on Judgement Day.
We really need a different book for that.
And that is the Bible
2 Timothy 3:16-17 Living Bible (TLB)
The whole Bible was given to us by inspiration from God and is useful
to teach us what is true and to make us realize what is wrong in our lives;
it straightens us out and helps us do what is right. It is God’s way of making us well prepared at every point, fully equipped to do good to everyone.
Now if following the instructions of the Holy Scriptures could save through faith in Jesus Christ
then these were not written by someone super evil - like the devil
The Scripture must have been authored by someone holy
1 John 1:5 New International Version (NIV)
This is the message we have heard from him and declare to you:
God is light; in him there is no darkness at all.
