1./ 1st, because it is the only version that tells about the vital & essential things that alone satisfy the initial questions of our lives.
2./ It ( like Jesus Christ ) is the primary target of denunciation and rejection: like as the world rejected Jesus Christ & destroyed His physical presence, so also, the world repudiates the KJV. It has been and is my experience now for 56 years that - the world does not want the truth around because the truth can demise and overthrow the status quo. e.g.
John 11:49-51 (King James Version)
49And one of them, named Caiaphas, being the high priest that same year, said unto them, Ye know nothing at all,
50Nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not.
51And this spake he not of himself: but being high priest that year, he prophesied that Jesus should die for that nation;
3./ How many times has the carnal reprobates of our times tried to destroy, burn and rid the world of ( not only the KJV ) Bible ? Yet, how often has the KJV been the subject of such attempted demise likewise, above all others ?
4./ It is not very difficult to spot and find and point out the truth : these kind stand out and stick out like sore thumbs: only, ask yourselves how many and why these have been slain in the process - and then you will know and understand the cost and price of truth: and, the sacrifice of it the world favors. Then, you will begin to find for yourselves why the KJV of the Bible is THE BIBLE.
5./ You will also find that, once you begin to believe and hold these truths ( which, "it" alone teaches ) esp. if you begin to publicly preach, tell and teach such things, that it will not take long for you also to be marked as
" one of them ": and, we all know why.
