Jehovah's Witnesses believe that God did preserve His Word down through the centuries. Consider just one experience with the Dead Sea Scrolls: "In one study, scholars compared the 53rd chapter of Isaiah in the Dead Sea Scroll with the Masoretic text produced a thousand years later. The book A General Introduction to the Bible, explains the results of the study: “Of the 166 words in Isaiah 53, there are only seventeen letters in question. Ten of these letters are simply a matter of spelling, which does not affect the sense. Four more letters are minor stylistic changes, such as conjunctions. The remaining three letters comprise the word ‘light,’ which is added in verse 11, and does not affect the meaning greatly. . . . Thus, in one chapter of 166 words, there is only one word (three letters) in question after a thousand years of transmission—and this word does not significantly change the meaning of the passage.” Yes we can have confidence in God's Word: “All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, that the man of God may be fully competent, completely equipped for every good work.” (2 Tim. 3:16, 17)

He did and they are not lost, just those manuscripts and copies are. God promised to preserve His holy Word forever. God's Word has been preserved over and throughout the centuries and even is today in the King James Bible. -In the Master's service. Thank you and God bless you!

Why indeed, if they were so important to humanity, did God not protect and preserve the original? Maybe it's an indication that their importance as a complete code of guidance was limited to a certain time and has ceased. God reveals his knowledge stage by stage, I suppose depending on man's readiness for each stage. HQ 2:255 says "He (God the Omnicient) knoweth what lies in their (mankind's) present and future and (what really happened in) their past. Nor shall they (mankind) ENCOMPASS AUGHT of His knowledge EXCEPT as He willeth (to release it)" God chose to associate his promise of scriptural preservation with the HQ. Clear indication that the HQ was meant to be the final revelation and coming at a time when the age of printing and mechanical reproduction and information technology was dawning upon us. In HQ 5:3 God says to mankind "This day have I perfected your religion for you, completed My favour upon you, and have chosen for you submission to My will (= Islam) as your religion." and in HQ 15:9 "We have, without doubt, sent down the Message (the HQ); and We WILL ASSUREDLY guard it (from corruption)"
