The Corruption of the Earth Before the Flood

The event

By the time we reach Genesis 6, the world Adam and Eve's descendants had built was in ruins morally, even as it multiplied numerically. "The Lord saw that the wickedness of man was great in the earth, and that every intention of the thoughts of his heart was only evil continually." It is one of the starkest verses in the whole Bible, and it sets the stage for the Flood account that follows.

Genesis 6:1-4 also describes the "sons of God" taking wives from among the "daughters of man" and the appearance of the Nephilim — a notoriously difficult passage that faithful evangelical scholars read in more than one way. Some see the godly line of Seth intermarrying with, and being absorbed into, Cain's corrupt line; others see more overtly supernatural rebellion behind the "sons of God" language. Bible-believing interpreters differ here on the details, but they agree on the point Moses is making: humanity's corruption had become total and unrestrained.

In the middle of that bleak picture, one line stands out like a candle in the dark: "Noah found favor in the eyes of the Lord." God's grief over human sin was real — Scripture doesn't flinch from saying He was "sorry that he had made man" and that "it grieved him to his heart" — but His grace toward one faithful man was just as real, and it is Noah's righteousness, not human merit in general, that becomes the hinge for everything that happens next.

Dating

Genesis 6:1-8 is not independently dated; it serves as the narrative prelude directly preceding the Flood account. The starting point here follows one traditional reading of God's statement in Genesis 6:3 that man's days would be "120 years" — taken as a period of grace before judgment (compare 1 Peter 3:20 on God's patience while the ark was prepared) and set 120 years before the traditional 2348 BC Flood date. Be aware that many interpreters, including many evangelicals, instead understand the 120 years as a new limit on human lifespan rather than a countdown to the Flood; on that reading this passage carries no fixed date at all beyond "shortly before the Flood." The identity of the "sons of God" and the Nephilim is genuinely debated among faithful evangelical interpreters (a supernatural rebellion vs. the godly line of Seth intermarrying with Cain's corrupt line); this is a disputed detail of interpretation, not a challenge to the passage's historicity.
