What does the Bible say about the days of Noah?

The Bible, particularly in Genesis 6 and Matthew 24, portrays the days of Noah as filled with corruption and a disregard for God. In Genesis 6:1-4, it is stated that men began to multiply on the earth but became wholly consumed by their sinful desires, leading to God's decision to bring about the flood. Matthew 24 draws a parallel between Noah's time and the days leading up to Christ's return, emphasizing that people would be preoccupied with daily activities without regard for the impending judgment. This serves as a warning to be vigilant and prepared for Christ's second coming, emphasizing the need for believers to live with an eternal perspective.
