Belief in God is rational.
Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED. (You could prove the first step a priori that everything has a cause by noting that nothing can come from nothing. This makes it a priori, not just an empirical observation).
I have vision about the importance of learning Torah as the central focus. But it is like a star in the center of a constellation of related values..
Some people have related values but lack the central focus.
The basic way this works is in the context of an authentic Litvak yeshiva. In such a place the areas of focus become clear.
