There has never been a extra-Biblical prophet proven to be 100% correct, of the complete truth of God required. Even all the cults have extra-Biblical "prophets," each and every one proven a liar by their false prophecies.
Anybody adding to the word of God, buyer beware.
Revelation 22
18 For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
19 And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
In any case, what sort of fool needs more than the Bible, the reliable word of God you couldn't know enough of in a lifetime?
It is the Word in the words you must listen to.
Only those who have ears to hear, can discern the Lords words speaking through His people.
When a few dozen Christians are speaking the same thing, while adding or subtracting some things because of their own imperfections, and knowing the Lords voice by familiarity of every day speaking then you will know the difference between what the Lord is saying and what men are saying.
People are reluctant to ask the Lord if something they hear is the truth or not because they do not have a running conversation both ways with the Lord every day.
It is easier to charge another with being a liar than to ask the Lord and let Him teach you, if you do not want to Him to overrule your own views and opinions.
The vision I had some years ago has been coming to pass for some time now, but my personal opinion of the vision has been a bit different,
not exactly as it has turned out.
