The Bible lists 7 generations between Noah and Seth. In this time the descendants of Adam and Eve began to ignore God and live in their sins. So by the time Noah has his children, his is the only godly family left on Earth! Can you imagine that? Sometimes it feels like we are the only Christians, but we know that others are out there. But for Noah, the Bible says he was it! By this time God is fed up with man! So he decides to fix this problem and start over with the only godly family left. So God tells Noah to build a giant boat. Now we need to understand how this looked to the people around Noah. Most people who study Bible times believe that up to this point it had never rained! The way the Earth works and looks now is believed to be very different from the Earth before the flood. So when Noah is building a boat, no one has ever seen rain, much less a flood! They would have no idea that the water could rise and cover the dry land. They had to think he was crazy! And, as you probably know, un-Godly people are not always nice when they tell you their opinion of something crazy. But Noah kept going because it we what God said to do and he was used to being different. This is the lesson we need to learn from Noah: God calls us to be different. We must follow him and trust that it will all work out because he sees the end. The world may think we are crazy, but God sees the big picture!
Activity idea: Find information on the water cycle or an experiment about how to make rain on the stovetop. Point out that God not only destroyed most of the men, but radically changed the Earth as well.
