The relationship between God and humanity is filled with highs and lows, yet it is fundamentally anchored in the mercy that flows directly from the source of life. Divine punishment and anger are never an end in themselves. Instead, they are strictly limited in duration out of consideration for the divine nature of the human soul. The primary approach among commentators is that the promise of an end to divine conflict is meant to comfort and reassure. God’s discipline against a sinner will not continue endlessly. Some view this as a historical promise to the people of Israel, assuring them that a day will come when God will remove their heart of stone and guide them on the proper path [רד״ק, אבן עזרא]. Others draw a deeper distinction between the types of divine discipline. Physical punishment is limited to a person's time in the material world. Furthermore, even spiritual anger—the hiding of God's face—will not last forever in the eternal world of souls, which exists entirely beyond the bounds of time [מלבי״ם].
God brings an end to His anger because He Himself is the creator of the human spirit and soul, and it is simply not right for Him to destroy His own handiwork [מצודת דוד, ביאור שטיינזלץ]. The soul is recognized as an exceptionally pure and eternal spiritual essence, possessing a rare, multifaceted nature to emphasize its greatness [שד״ל]. There is a subtle difference between these inner forces: the spirit serves as the life force granted to a person from God, while the soul represents the most exalted, divine piece that God crafted Himself [מלבי״ם].
The exact dynamic that triggers God's mercy is understood in two distinct ways. One perspective associates the spirit's condition with weakness, fainting, and submission. According to this line of thought, the moment the human spirit yields, surrenders, and admits its wrongs, God immediately drops His anger [רש״י, ביאור שטיינזלץ]. Similarly, if God were to remain angry forever, the fragile human spirit would simply wither and die out, prompting God to act with compassion toward His creations [אבן עזרא, שד״ל].
A second approach views the spirit's condition in terms of being wrapped or clothed. From this viewpoint, the pure divine spirit is enveloped within a physical body. Because the body is formed from the earth, it naturally leans toward sin and material desires. God placed the spirit inside a person specifically to overcome these physical urges and guide the body toward good. Recognizing the built-in conflict of a pure soul trapped inside a heavy, material form, God chooses not to prolong His anger, showing deep compassion for the everyday human struggle [רד״ק, מצודת ציון, שד״ל, צאינה וראינה].
