When you consider what kind of opposition the Bible has had throughout history, it is a wonder that any of it has been preserved to our day. Yet just as this proverb says, God had preserved His knowledge - as well as the writings of many other godly men - even though it has often been attempted to be destroyed by evil men.
What is often lost to us are the words of the treacherous men who have lived throughout history. But even more than that we see that their very words themselves have been overthrown. The "who's who" list of evil men who have predicted the demise of God and His Word is so long that I would not have room to list them all in a post here - yet all their words have been overthrown. They have risen to predict that God would be destroyed - only to see Him remain and continue to change history through His Word and His church.
How frustrating it has to be to see generation after generation continuing to be transformed by the gospel. How frustrating to see the very same gospel that they've hated for generations stand in another generation as their wicked philosophies were thrown on the trash heap of history.
It is wonderful to see the stories of men like John Hus and John Wycliffe and how God preserved their works - especially their translations of the Bible. Both men saw the false church react strongly to their translation of the Scriptures - especially since their translations were trying to put God's Word into the language of the people. The false church killed John Hus - and were so disgusted with Wycliffe that over 40 years after his death dug up his bones and burned them and condemned him. But God preserved the writings and knowledge that these men gave to us - eventually using both of them as precursors to the Reformation. Rather than destroy the knowledge that they brought to us - God preserved it and used it to overthrow all the treacherous words and actions of the godless church that tried to overthrow the Word of God.
Here is wisdom . . . realizing that God's Word will stand when everything else has faded away. As Peter said, 'All flesh is like grass, and all its flory like the flower of the grass. The grass withers, and the flower falls off, but the Word of the Lord endures forever." (1 Peter 1:24-25, NASB)
