NOPE...
the Holy Spirit does, through the authors he inspired to write down word of God...
Also, don't pretierists determine themselves which prophecies get spiritualized and explained away?
Let me get this out of the way first, a side note: I think we have Spurgeon to thank for that unhappy, unperceptive phrase, "spiritualize away".
"spiritualized and explained away". Now think about your phrase for a moment. This is a core problem of many of the futurist/literalists. They equate spiritualizing with "spiritualizing away", which is equated with "explaining away".
This shows that any discussion on these points would be futile - as long as your hurdle remains. Spiritualizing, which is simply giving a spiritual interpretation, is found throughout the Bible. Consider Paul's spiritualizing to the Galatians:
Gal. 4:22-26
22 For it is written that Abraham had two sons: the one by a bondwoman, the other by a freewoman. 23 But he who was of the bondwoman was born according to the flesh, and he of the freewoman through promise, 24 which things are symbolic. For these are the two covenants: the one from Mount Sinai which gives birth to bondage, which is Hagar— 25 for this Hagar is Mount Sinai in Arabia, and corresponds to Jerusalem which now is, and is in bondage with her children— 26 but the Jerusalem above is free, which is the mother of us all.
Poor Paul! He must not believe that Abraham really had two sons, seeing that he explained them away. And then he compounds his error by confusing Hagar with the city of Jerusalem!
And what about Jesus? Those staunch literalist Jews were righteously vexed when he explained away their temple by his ridiculous assertion of rebuilding it in three days. At least, that is what it sounded like to them.
Paul shows us that those things that some make fun of because they are invisible, are actually eternal. It is reality, pure and simple. You say "spiritualize", I say "spiritual eyes".
"while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal." - 2 Cor. 4:18
"9 But as it is written:
“ Eye has not seen, nor ear heard,
Nor have entered into the heart of man
The things which God has prepared for those who love Him."
10 But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. 11 For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. 12 Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God." - 1Cor. 2:9-12
"Now faith is the substance of things hoped for, the evidence of things not seen." - Heb. 11:1
Very much of what the Bible teaches is invisible. It is a major emphasis. And these invisible things are spiritually understood - and literally misunderstood. This is where faith comes from, the virtue that has confidence in things unseen.
