Previously noted there are three types of Jewish instructions: Chukkim, Eidot, Mishpatim. Eidot and Mishpatim have reasons, rationales, intentions. Chukim don’t. Same in life: we do people favors which we think are reasonable. But the test of a relationship is to do meet an unreasonable request. When you trust the other, then you do it despite its apparent non rationality. Chukim are the same vis a vis G-d.
