You are referring to what Jesus told His disciples about His second coming, shortly before His death. He said, “As it was in the days of Noah, so it will be at the coming of the Son of Man” (Matthew 24:37).

He then explained that He wasn’t talking about another great flood like Noah’s, but on people’s attitude just before it came. He said, “In the days before the flood, people were eating and drinking, marrying and giving in marriage … and they knew nothing about what would happen until the flood came and took them all away” (Matthew 24:38-39).

In other words, just before the flood, people were doing what they always do—eating, drinking, marrying and so forth. But in the midst of it all, they ignored Noah’s warnings and deliberately turned their backs on God. They had ample warning of God’s coming judgment but they refused to believe, and were swept away as a result.

It will be the same, Jesus said, before He returns. Most people will ignore God’s Word and go on living their lives as if God didn’t even exist. But suddenly, time will run out, Christ will return—and then it will be too late. But it doesn’t need to be this way! When we know Christ, we have no reason to fear the future, because we belong to Him forever. Are you ready for that day? You can be, by giving your life to Christ.
