Human suffering is often viewed as a destructive force, yet it actually serves as a complex process of spiritual repair where pain and recovery are deeply intertwined. The primary approach among commentators is that the very same hands of God that deliver a painful blow are also the ones that bring comfort and healing. The pain itself acts as the medicine. Hardship cleanses a person of their wrongdoings, much like a patient who must swallow a bitter remedy where the bitterness itself holds the secret to returning to full health [מצודת דוד, מלבי״ם].
This process of spiritual repair addresses both the past and the future [מלבי״ם]. One aspect of suffering serves as a gentle correction to guide a person's future path. Just as a bandage is applied to keep a physical infection from spreading, this type of hardship restricts a person and prevents them from committing further wrongs. A second, more severe type of suffering is designed to scrub away the stains of sins that have already been committed in the past.
There are also different degrees of hardship that involve different aspects of God's interaction with the world [אלשיך]. Mild challenges, often experienced by the righteous out of divine love, are guided entirely by His mercy. However, a massive, crushing blow meant to deeply cleanse a person requires a combination of forces. This duality is reflected in a subtle tradition regarding how the word for God's hands is read and written [מנחת שי]. It is spoken as a plural word to hint at two distinct forces working in harmony: the hand of strict justice that delivers the blow, and the hand of mercy that provides the strength to endure the pain. At the same time, it is written as a singular word to teach that these two forces are completely united in a single, purposeful act of healing. Ultimately, it is far better for a person to endure hardship and be healed directly by God's hands in this world, rather than facing punishment from destructive forces in the world to come [אלשיך].
