nothing of Deuteronomy 32 has anything to do with acts 2 or 1cor chapter 12 to 14.
Deuteronmoy 32 is essential in understanding the foundation the word faith as to how it is used through the scriptures. The phrase "no faith" reveals natural unconverted man .All men are born with none. Doubt is not the opposite of faith again "no faith" not believing God but trusting in the imaginations of their own heart is. The fool.
"No faith" is the same thing as saying" no relationship" with God. It is shown like in the foundation of the tongue doctrine in Isiah 28 " yet they
would not hear or they refused to beleive" and again when the law is defined deeper in 1 Corinthians 14:21-22 "yet for all that will they
not hear me, saith the Lord". In other word they refused to believe the word of God prophecy in any language to include their own tongue.
For with stammering lips and another tongue will he speak to this people. To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing:
yet they would not hear.Isiah 28:11-12
In the law it is written, With men of other tongues and other lips will I speak unto this people; and
yet for all that will they not hear me, saith the Lord. Wherefore tongues
are for a sign,
not to them that believe, but to them that "believe not"
(no faith) but prophesying
(exercising the faith of Christ)) serveth
not for them that believe not,
(no faith) but for them which believe. 1 Corinthians 14:21-22
Those in Acts 2 heard the word spoken of Peter but again because they did not mix faith (believe God) they said the men where drunk .
So then its not just hearing but mixing faith or believing God that can soften our hearts in confirmation that we have exercised His faith that works in us to both will and do His good pleasure. .
Deuteronomy 32 speaks of those who have "no faith" again not little by none.. It describes natural man that neither has knowledge of God or has knowledge and is a stranger to the promises it in exchange for the oral traditions of men like revealed in Jerimiah 44. It describes a fool no God working in a person heart. No difference, no faith, no God in their heart as a hearing coming from God.
Also you assume they had no understnsding. if you would have just started from verse 7 you would have seen they had more than understanding they had arelationship with God as they had for generations.
"I person must hear God and by that hearing, believe God .If they hear and do not belive it shows they have no faith
Those who have no faith can hear the word of God like with the section you offered and not believe God like the example I use with Jerimiah 44.
Those in Isiah 28 did not believe the word of God as prophecy even in their own Hebrew tongue, again they mocked God after the manner spoken of in Jerimiah 44 indicating they were a froward nation of "no faith".
As for the
word that thou hast spoken unto us in the
name of the Lord, we
will not hearken unto thee. But
we will certainly do whatsoever thing goeth forth out of our own mouth, to burn incense unto the queen of heaven, and to pour out drink offerings unto her, as we have done, we, and our fathers, our kings, and our princes, in the cities of Judah, and in the streets of Jerusalem: for then had we plenty of victuals, and were well, and saw no evil. Jerimiah 44
Big stretch you try to do. Babylon(babble) has nothing to do with 1cor 12 to 14 of anything in Acts or 1cor. That was in gen, and it was not contextual to the gifts of the Holy Spirit. Very bad allegorizing
Having a faith that comes from hearing God is the contextual gift of the Holy Spirit. without it babbling occurs as oral traditions of men like this tongue doctrine that men turn the sign upside down that shows they have no faith to making it a faith by them making a noise without meaning called babbling total confusion.
The babbling Babylonians were confused to who God was and how they could understand him who has no form so they could seek after Him .They had no faith as it is written by which they could understand God. Every man had his own private interpretation. Again they wanted to build a tower that was as high as their imagination as in out of sight out of sight. There was no walking by faith nothing but babble when it came to understanding God.
