Where is the netziv he’s quoting? That seems to be untenable as per the rambams ikrei emunah. Perhaps Avrohom revealed hashgocha, but he didn’t change the way Hashem runs the world. To think that only the big picture matters is an opinion of many Greek philosophers, not gedolei yisroel.
The other quotes I’m not going to comment on, as the conclusions he draws from them are conjecture and extrapolation.
