-- When you hear people saying that "the entire New Testament can be RECONSTRUCTED", you know that they are people who do not believe that God kept His promise about "the words of the LORD" to "PRESERVE them from this generation FOR EVER" (as God said in Psalms 12:6-7 see also Psalms 119:152, 160; 1 Peter 1:25). There are numerous web links which have the facts and substantially agree with each other. I am including 2 such web links for you to view for yourself.

-- Even more reliable than these web links is the internal evidence in the Bible itself. There are no errors in the King James Version which came largely from the Textus Receptus (Received Text of about 5300 manuscripts still in existence)(not 25000). I read, study, and recommend ONLY the King James version Bible because I will not trust a bible with even one mistake in it. 

-- If you have access to a non-King James bible, check Mark 1:2 in it. See if it says that the Mark 1:2 prophecy "Behold, I send my messenger before thy face..." is "IN ISAIAH", as all translations EXCEPT the King James Bible say, since 1900. The King James Bible translates it correctly that it is found "IN THE PHOPHETS" (rather than in Isaiah). Sure enough, the Mark 1:2 statement "Behold, I send my messenger before thy face...." is NOWHERE in Isaiah, and is ONLY FOUND IN MALACHI 3:1. The King James Bible is error free, but the modern translations have an error in Mark 1:2. -- Is one mistake too much for you? It is for me. 

-- How about two mistakes? Is two mistakes too many for you. Check in your non-King James Bible in Hebrews 3:16-17. The King James Bible says that "some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses." So, the King James leaves room for some to have come out of Egypt WITHOUT provoking God and dying in the wilderness. Now see if your NON-King James translation also leaves room for some to have come out of Egypt WITHOUT provoking God and dying in the wilderness. All the modern translations, that sell as bibles, say that ALL that came out of Egypt with Moses provoked (rebelled) and died in the wilderness (verse 17). OK, well look in that same book in Numbers 26:65 to see that the same book called a "bible" contradicts Hebrews 3:16-17 by saying that there were two people who came out of Egypt with Moses who did NOT provoke or rebel, and did NOT die in the wilderness, but they eventually were the only two adults to both leave Egypt and also to enter Canaan. The King James Bible leaves room for them by being translated that "NOT ALL that came out of Egypt (did provoke). 

-- There are many, many more examples which expose the difference between the King James Version Bible translated from the Received (over 5000) Text copied and handed down through the churches established by the apostle Paul, (...the difference between it) and all the other translations from the minority (2 texts) Alexandrian text, the manuscripts of which do not even agree with each other. The King James Bible is errorless. All the modern translations of the corrupted Alexandrian text have errors in them. In the important areas, they are so different from the majority, received text in the King James Bible, that they CAN NOT both be the word of God. The King James Version Bible is the word of God for English speaking people.
