Human beings have always struggled to understand the deep workings of divine justice, especially the complex balance of reward and punishment in the world. Because our lifespans are so short and filled with the constant rush of daily life, it is difficult to gain the wisdom needed to truly grasp how God reacts to human behavior. It is hard to know exactly what triggers His anger and how to protect oneself from it [רש״י, מצודת דוד, ביאור שטיינזלץ].
This lack of understanding often leads to confusion when people see wicked individuals succeeding. What many fail to realize is that the true power of God's anger is actually shown through His enormous self-restraint. He extends His patience toward the wicked over many decades, rewarding them in this world for the few good deeds they may have done, while keeping their severe, ultimate punishment hidden from our view [אלשיך, מאירי]. Indeed, some maintain that only a truly wise person or a prophet has the ability to reach a genuine understanding of this divine justice [אבן עזרא בשם רבי משה].
At the same time, the intensity of God's anger is directly tied to the level of reverence a person holds for Him. The primary approach among commentators is that this dynamic explains why righteous people often suffer. God judges His devoted followers with absolute precision. The closer a person is to God and the more they revere Him, the stricter the standard of justice applied to them, holding them accountable for even the slightest missteps [רד״ק, אבן עזרא, אלשיך, מאירי]. A person who tries to justify their own actions in this world ultimately invites this highly exact heavenly judgment upon themselves [תורה תמימה].
Alternatively, this relationship can be seen as a direct equation: just as God is inherently worthy of fear and awe, His anger is equally severe when brought upon sinners [רש״י]. Another perspective ties all these realities together through the theme of the unknown. Just as the perfect and proper way to revere God remains hidden from human understanding, the exact reasons behind His anger and strict judgment remain a mystery as well [מצודת דוד].
