What presuppositions make every prophecy into a lie?

On a religion forum someone posted and asked, “Are there ANY Bible prophecies that indisputably came true?”  Immediately rock solid prophecies leapt to mind and to keyboard: Abraham and Sarah having Isaac in their old age, God promising to grow a mighty nation of the Jews in Egypt, God telling Moses that he will lead the nation out of Egypt, Isaiah prophesying that God would release the Jews from Babylonian captivity to rebuild Jerusalem, Daniel naming the kings of coming empires, and that the Messiah would be born in Bethlehem. 

Rock solid?  As I soon learned, every prophecy in the Bible was rejected by the skeptics along with every secular source that supported the biblical accounts.  It turned out the poster and the skeptics had ironclad rules they had hidden from view but followed rigidly.  By the time the hidden rules of the presupposition game were slowly revealed in the words of the skeptics, the answer they had predetermined to obtain for themselves was, “No, there never was and never will be an indisputable biblical prophecy because our rules have guaranteed this answer for us.”

The hidden rules of the presupposition game are:

1. If a prophecy was made in one book of the Old Testament and fulfilled in another book of the Old Testament it must always be assumed that the prophecy was a recent scribal edit added after the fact (about 400 BC) and did not exist in the first writing of the book.
2. If a prophecy was made in the Old Testament regarding the future Messiah (e.g. virgin birth, born in Bethlehem, died via crucifixion, resurrected from the dead) then whenever the New Testament demonstrates that Jesus fulfilled that prophecy it must be assumed that the gospel writer invented those details about Jesus and that they never actually happened to Jesus.
3. If a prophecy was made by a New Testament person (e.g. Jesus predicted the destruction of the temple which occurred in 70 AD) then it must always be assumed that the prophecy was written down after the prophetic event was fulfilled and was not actually uttered at the time described in the writing.

What is the implication if every Bible prophecy is a lie?

In short, the hidden rules of the anti-supernatural presuppositionalists guarantee that no biblical prophecy can ever be accepted as valid prophecy.  Worse, it automatically makes every Old Testament book of the Bible a fabrication filled with falsehoods and every New Testament apostle that wrote a letter or endorsed a gospel account to be a flagrant liar. 

Virtually the entire Christian faith is dependent on the truths that Jesus was born of a virgin, was born in Bethlehem as a descendant of David, lived a perfect life, died a sacrificial death, and resurrected from death to life.  Since all those events were first prophesied in the Old Testament about the Messiah, it means that either Jesus fulfilled them all and was the Messiah, or, every foundational aspect of Christianity is a brazen lie and never happened. 

In other words, if one accepts that Jesus did live a perfect life, and/or died a sacrificial death via crucifixion, and/or resurrected from death to life, then you have “personal proof” that at least five Old Testament prophecies absolutely were fulfilled. 

Opposite that, if one accepts that the gospel writers and the apostles all lied in their writings about such things as Jesus being born of a virgin, Jesus being born in Bethlehem in the line of David, His perfect life, His sacrificial death by crucifixion, and His resurrection to life, then EVERY aspect of Christianity is false and immoral; all of it having been based on falsehoods.  There can be nothing good or wholesome in the Christian religion in such a case for it is all comprised of deceit, errors, and intentional mis-directions.

No revelation of God is possible?

Now, if every Bible prophecy is a fabrication and was never made in real human history, then God never revealed Himself in it or through it, ever.  For example, Abraham could never have encountered God because God always prophesied the future (including a son and a nation) to Abraham on every encounter.  Certainly Moses never encountered God because at the burning bush God supposedly prophesied that Moses would lead the nation out of Egypt into the promised land originally granted to Abraham (a prophecy later fulfilled by Joshua).

Kind David was given a future-telling prophecy that his lineage would rule Israel for eternity and would save all the world from their sins.  That too had to have been a lie, a fake future-telling prophecy, a fabrication added to the scrolls by devious scribes in 400 BC. 

Was every prophecy of the Messiah a future-telling prophecy?

And the worst part, there never was a promised Messiah.  Every promise of a Savior/Messiah in the Old Testament was a future-telling prophecy.  Every one.  If all of those prophecies were recent edits by sneaky Jewish scribes in 400 BC and were not made by the original prophets who first wrote the books, or, if they were never fulfilled by anyone, including Jesus, then the world never did have a Messiah from the line of David.  No Messiah means no sacrifice was made for sins.  No sacrifice for sins means no forgiveness and no salvation.  None. 

Were the first manuscripts of the Bible written without any future-telling prophecies?

It is wrongly assumed by the skeptics that the Bible was originally a book that told a story about religious men and had no future-telling prophecies.  They suppose that as time went on and the people described in the books died, the books were edited to describe past historical events as if they had been forecasted by the religious men. 

Such a theory completely ignores the fact that the Bible is nothing but one continuous future-telling prophecy from one page to the next.  There are no stories that do not contain future-telling prophecies.  The prophecies were often the point, motivation, and plot behind each recorded event.  There can be no story of Moses without all the future-telling prophecies by which God directed him and ultimately delivered the Law.  Take away the future-telling prophecies because you assume they never happened in the manner described in the Bible, and there is no book of religious men.

What choice do I have but to believe the prophecies of the Bible are valid?

That about sums up the two choices: 

1. Every patriarch in the Bible is a liar for having claimed an encounter with God and having claimed to have been given a future-telling prophecy regarding a promised land, a great nation, or a coming Messiah, thus, all of Judaism and all of Christianity are a giant conspiracy of uncounted liars covering a span of four thousand years.

-Or-

2. The prophecies were presented to the original patriarchs just as the Scriptures report them and Jesus is the fulfillment of every one of the prophecies just as the gospels, apostles, and eyewitnesses have reported. 

Which choice is backed by the best evidence and is more plausible?  If you have a presupposition that everything supernatural is impossible, you will choose option one.  If you presuppose a living personal God who loves His creation and has communicated with it, option two may have some appeal for you.

As for me and my house, we have chosen to believe in the Lord.
