God makes the demand shockingly small. Tanna DeBei Eliyahu Rabbah 26:1 does not open with sacrifices, pilgrimages, secrets, or heroic suffering. God turns to Israel and says: My children, what do I seek from you? Only this. Love one another. Honor one another. Have awe for one another.
The simplicity is the pressure. Love is not sentiment if it never changes how one Jew treats another. Honor is not politeness if it disappears when status is uneven. Awe is not fear. It is the trembling recognition that another human being is not an obstacle, a tool, or background noise, but a soul standing before God.
The midrash places communal dignity at the center of covenant life. Israel does not become holy by despising itself from within. It becomes holy when its members learn to look at one another with enough reverence that cruelty starts to feel like sacrilege.
God asks for no more than that. The word "only" makes the command sound light until a person tries to live it for one full day.
