Lamech lived one hundred and eighty-two years, and became the father of a son. (Genesis 5:28)Who was alive when Noah was born? What was the state of the world? Lamech, Noah's father, was born 874 years after creation (see State of the World: Lamech's Birth). After Lamech had lived for 182 years, he became the father of one of the most well known men in all of history. Noah was born. But the world that Noah was born into was very different from the world that his father was born into.
Noah was born 1056 years after creation (2948 BC according to Ussher's timeline). At this point in history, Adam had been dead for 126 years. Seth had been dead for just 14 years. Men were beginning to die, but not from the human sword. Men were dying because of the curse which was proclaimed over all of humanity in the garden. Men were dying because of sin.
After thousands of years of war and disease, death seems normal. But death must have been a frightening and mysterious reality to the earliest humans. Imagine the sense of desperation that must have been present at this moment in history. Men were beginning to clearly see another terrifying consequence of the fall— natural death (and it was quickly becoming more frequent).
When Lamech was born, men were numerous and wicked. When Noah was born, men were more numerous and more wicked. And with the departure of Enoch 69 years before Noah's birth, the righteous men of the earth must have been growing more and more restless. Perhaps a slight sense of hopelessness had overcome the righteous remnant which remained on the earth. It was into this world that Noah was born— a world that was beginning to feel the pangs of death— a world that continued multiplying its wickedness...
