What does the Bible say about God's judgment in Noah's day?

The account of the flood in Noah's day serves as a vivid representation of God's judgment against sin. In Genesis 6:17, God explicitly tells Noah that He will bring a flood to destroy all flesh that has the breath of life. This judgment reflects the serious nature of human wickedness, as God saw that every imagination of man's heart was only evil continually (Genesis 6:5). The flood illustrates not only God's wrath but also His righteousness, as He does not ignore sin but holds humanity accountable for their actions.
