bryan1276... First of all I believe that God did preserve his words, it's just that, it seems that alot of KJVO (especially in WV) love to quote PS 12:6,7 as a proof text. It does not prove, in that passage, that God preserves his words, but he preserves his people (even the dead in Christ are preserved in heaven!) I'll agree that God has preserved his words - in the many manuscripts that have been handed down. By just looking at the 1000's of copies we have to compare, proves that God preserves his words. No other writing over 2000 years old has as many copies. We are the most blessed people in the world to have so many good translations of God's Word. We should be thanking God for blessing us with translations that even an uneducated man can read and understand, instead of trying to prove that only one translation is the correct one.
I looked at the five passages you listed, and none prove KJV is the only preserved word.
Matt 24:35 I agree totally -- Everything Christ says is true, and shall come to pass. Notice the context is prophecy. Everything Christ prophecied will happen, and his prophecies will not pass away until it does.
Ps.119:89 This passage does not prove that when the KJV was translated, and finished, that God declared "That's it, That's the perfect Bible." Notice that the writer used the word "is". That means present tense. They (God's words)were already settled way before 1611. The word "settle" means to stand up, to erect, to set in place, to make firm, as one would a column (Gen 35:20) or altar (Gen 33:20), or monument (1 Sam 15:12) It means that what God has promised will be sure forever.
1 Sam 3:19 This simply means that all of Samuels words were fulfilled.
1 Pet. 1:23-25 the "word" here is clearly the gospel (good news), as the plan of salvation. When I first read vs 23 I thought it could be talking about Christ (The Word) but in it's proper context it clearly means the gospel.
In the International Standard Version it plainly states in vs 25 "but the word of the Lord lasts forever. Now this word is the good news that was announced to you."
And last but not least, Isa 40:8, Again, what God says - you can take to the bank. If he says it will happen -- it will. By the way, what does it mean to "take someone at their word"? Doesn't that mean you can trust them to keep their promises. All five passages simply means that you can take God at his word. His promises are settled in Heaven, and not one will pass away until they come true. God outlined the plan of salvation and that is the only way to Him.
