An exhibition at the Field Museum in Chicago displays a particularly radiant set of diamonds known as "colorless diamonds." These diamonds are some of the most precious stones in all the earth. This is because, unlike most diamonds, they lack the slightest tint of yellow or brown.
In a similar way, the purity of the Bible sets it apart from all other writings. Scripture is distinguished as the highest of books because it does not contain even the slightest fleck of immorality or sinful corruption.
Every human composition, no matter how virtuous it may be in its content, bears some fatal flaw. The taint of sin will be found in it to one degree or another. It may say many wonderful things. It may give much wisdom. But somewhere or somehow it will promote sin and show its earthly origin.
The Bible, however, reveals itself to be divine in nature because it reflects the perfect purity of God Himself. This is why the Christian scriptures have become known throughout history as "the Holy Bible." No other book can bear such an epitaph because no other book can be said to be flawless in doctrine and spotless in moral virtue.
This doesn't mean the Bible is without its detractors. Many men seek to assail the purity of the Scriptures. Many scoffers have said that it promotes murder (i.e. the extermination of the Canaanites), diminishes human dignity (slavery), and presents a sadistic God (one who sacrifices His Son).
But such attacks are without grounds and arise only from a spirit of animosity. The holiness of the Bible is easily discovered when one reads through it.
It doesn't take long to see how vigorously it denounces sin and shows how abhorrent it really is. Never once does it condone the slightest evil or allow for its indulgence. Instead, it roots out sin from the most secret recesses of the heart, guards against it, and leads only to a life of holiness.
To be sure, this is why most people will not dare to read the Bible: they fear it will expose their guilt, remind them of God's vengeance, and lead them away from the corruptions they currently enjoy.
But if you ever needed assurance that the Bible is God's word, all you have to do is read it. It validates itself. As you examine it you will find that each page bears the insignia of a holy God. To be sure, "Every word of God is flawless." Prov. 30:5
