מלאכי, פרק ג׳, פסוק י״ח

In the future day of judgment, the true nature of reality will become clear, and God's justice, which often remains hidden in this world, will finally be revealed to all. Today, it frequently appears that wicked people live in peace while those who serve God suffer. This confusing reality leads people to mistakenly believe that God favors bad deeds and that there is no benefit in serving Him. However, in the future, the truth will become public, and the stark contrast between the righteous and the wicked will be proven and easily understood [מצודת דוד, רד״ק, ביאור שטיינזלץ, צאינה וראינה]. Directed specifically to the people of that generation, this message also stands as the final conclusion of all prophecies [אבן עזרא].

The promise of a future return is understood primarily as a return to clear vision, allowing humanity to properly distinguish between good and evil. Yet, another approach interprets this return literally, viewing it as a promise that the dead will be brought back to life in this world [מלבי״ם].

A clear comparison is drawn between the righteous and the wicked, as well as between the one who serves God and the one who does not. One perspective views this simply as a repetition designed to emphasize the massive gap between those who do good and those who do evil [מצודת דוד]. Another approach, however, sees a much deeper, twofold distinction. It is not just about separating the righteous from the wicked, but also about identifying differences among the righteous themselves. The act of serving implies intense, demanding work. Therefore, a person might be completely righteous yet still not qualify as an active worker. According to this view, the real difference lies in a person's internal motivation. A true servant of God acts out of pure love, without expecting any reward. In contrast, the one who does not serve is still a righteous person, but acts out of a fear of punishment or a desire for a reward. This makes them more like a hired worker looking out for themselves than a deeply loyal servant. While both individuals are fully righteous, a spiritual gap exists between them. This gap is compared to the subtle but important difference between a person who reviews their studies a hundred times and one who pushes themselves to put in the extra effort to review it a hundred and one times [מלבי״ם].
