Facing hardship and pain requires a deep sense of acceptance, rooted in the belief that God acts with absolute fairness and justice. The primary approach among commentators is that the troubles and suffering a person endures are brought about justly, even when life unfolds contrary to their desires [מאירי, שטיינזלץ]. This recognition grows from an understanding of the Torah [רד״ק], alongside a personal realization that such hardships serve as a fitting and rightful judgment for past mistakes [מלבי״ם].
The mental anguish and affliction that the poet faced repeatedly [אבן עזרא, מצודת דוד] were not random. Instead, they were delivered with honesty, truth, and absolute faithfulness [רש״י, רד״ק].
Beyond simply justifying the hardship, there is a much deeper purpose to this suffering. Affliction is not merely a punishment; rather, it is a profound expression of God's loyalty. Hardships enter a person's life to cleanse them of their sins and guide them toward repentance. Ultimately, this process clears the way for God to fulfill His positive promises, allowing Him to bestow future kindness upon the individual [מלבי״ם].
