Question

Why does the Rabbi categorically reject the explanation that God really does conceal His intervention from us? Or in your words—plays hide-and-seek with us… Obviously otherwise there is no test, and it is not for nothing that blessing rests only on something hidden from the eye.
In the end, God also pretty much hides the fact that He created the world…
I claim this because there are seemingly explicit verses that follow this line throughout the Hebrew Bible (Tanakh), prophecies about the future to come, and in general reward for commandments in this world, like sending away the mother bird.
P.S. Assuming that the soul really does affect choice or one thing or another—it can easily be said that God does indeed have an influence, since it comes out through tools that cannot be measured.
