If a person refuses to listen when other people try to help him, then he will bring trouble to himself. But the person who respects the things other people tell him, will be rewarded.
Noah was warned by God about things that Noah could not yet see. But Noah had faith and respect for God. So Noah built a large boat to save his family. With his faith, Noah showed that the world was wrong. And Noah became one of those people who are made right with God through faith.
