Not nessescarily, i believe insight comes from God,
I do believe however that It has given many proofs and supporting evidence for the Quran, although that depends on your definition of 'code 19'
I believe Gods Criterion is loaded with mathematical evidences for various things. and i believe that the number 19, and the word Wahd are Gods signature of authenticity
19 = 1, 9 (The First and the Last), add them together you get One Zero (one circle), or one without beginning or end, all encompassing. or The Circle (theo) which means God. The arabic word Wahd has a numerical value of 19, again linking 19 to One, Allah (The One God).
Theese are just little observations i have made, some may call them coincidences, and i believe they are, however, not, (as many people have come to interpret coincidences to mean) Unintentional. Its Gods will, his proofs are there.
again in regards to the Insight provided by the discovery of this, in terms of insight into understanding Our duties and the law god has ordained, i dont believe it has given much insight, however, It more than anything seems to be a proof, more evidence for the Qurans, as God says he sends down proofs with his messengers.
I also believe its an awe-inspiring glimpse of the intricacy of Gods creation, which is a great miracle, and certainly has played a major part in me realizing the exsistense and Awesomeness of God.
Something i just thought of yesterday, and i believe God gave me a glimpse of understanding of, in regards to God (the One), 19 (his signature), the Quran (his criterion) i believe:
that the "Numericaly structured Books" of 'ilyeen and sijeen' are the Quran. because it says 'the record of the righteous, the record of the wicked'. The Quran is a numericaly structured book, and it is a record of righteous people and wicked.
Theese are all ovbiously multiple-meaning verses, and i am cautious to assert anything about them, and as such this is only my personal belief, i do believe that God has given me some insight into them though, as it seems that this is the way He does, in that i ask for understanding, forget about it, and days, months, or even years later i just have a sudden insight that seems to make sense
I believe theese verses (and concept) is related to the 'Over it is 19' verse in the 'Hidden Secret' Surah (surah 74 if i recall correctly).
While i dont realy understand it very well, i believe its all talking about the concept of Gods Criterion (quran), Signed by Gods signature (19), which is a numericaly structured book, which contains a record or account of the wicked and the righteous (i.e the ilyeen and sijeen), Which God says will be a witness against us (unless im recalling incorrectly) on the day of judgement.
In other words,
Gods Quran is the criterion, to whether we get into Heaven or Hell.
We (should) know this..
as i said, i dont believe its given us new insight into what is nesseccary for our salvation, but it is just further proof that God is unravelling, so that in this day and age of information and so many contradicting views etc, we may know what is true, becuase more and more proofs are being shown to us by God in the Quran.
I dont know if what i was trying to explain is clear, but i do see strong connections, i dont quite understand yet in theese verses, and to be honest, itis not important, as the clear and straight forward verses are the essense of the Quran, however personaly it has increased my belief, and proof in my mind
If i am Guided it is because God has guided me, and if i stray it is a result of my wrongdoing. At the end of the day, God knows and i do not know
