Even though they contain different truths? Is God the author of confusion? The lost world thinks we are crazy to have more than one Bible and each contains different truths. And yet we base our beliefs off the word of God...bizarre.
or it could also be that the KJV was a translation made in the early 1600's, and while it is fine, some 500 years later more translations have been made in modern and different languages , and they are fine to use to. so, God's word has been preserved, but not in the 1611 version only.
