This passage is often misinterpreted as promoting moral relativism or nihilism, implying no ultimate difference between good and evil or that righteous living is futile since all share the same fate, but it specifically addresses observable events in temporal existence under the sun, not denying God's eternal justice, rewards, or judgments as clarified elsewhere in Scripture like the New Testament's teachings on afterlife accountability.
Ecclesiastes 9:2
King James Version (1769)
2 All things come alike to all: there is one event to the righteous, and to the wicked; to the good and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as is the good, so is the sinner; and he that sweareth, as he that feareth an oath.
Ecclesiastes 9:2 conveys the sobering reality that under the sun, death befalls all people alike, regardless of their righteousness, wickedness, goodness, uncleanness, religious observance, or moral character, emphasizing the impartiality of mortality in earthly life and the vanity of expecting immediate divine justice here, which prompts reflection on life's fleeting nature and the pursuit of wisdom and godliness amid such uncertainties.
