Firstly, accepting for discussion your mind, heart, will analysis, I just read what's there. What they heard stabbed them in the heart.
I don't find this to be a unique experience for human beings to hear something that does this to them. These Jews just became convinced they'd killed the Jewish Messiah/King the Jews had been awaiting for many generations.
And in this section, we're not clearly told that some didn't believe.
So, for me it's similar to the soils parable we're discussing on the other thread, where we're only told so much and then we speculate by trying to debatably insert things.
I'm going to go to the other thread so won't be answering you here.
