The main idea of Genesis chapter 6 verses 5-22 is that God was tired of the sin that was spreading throughout the population so he decided that he would bring a flood upon them. The first thing that happened was God saw the creation of sin so then he decided to that he wanted to start over. By this he was going to bring chaos upon the sinners but before the chaos began he allowed Noah to build an ark as he found faith and value in Noah and knew he wasn’t like the others. That way Noah could support himself and as well as his family and two of each creature/animal as they were favorited. A life lesson that us people can learn from this passage is that God can and will destroy the land and life he gave us as a gift if we don’t appreciate it or take advantage of it for bad things.
"When the Lord saw how great the wickedness of human beings was on earth, and how every desire that their heart conceived was always nothing but evil* the Lord regretted making human beings on the earth, and his heart was grieved. So the Lord said: I will wipe out from the earth the human beings I have created" (Gn 6:5-7).
"But Noah found favor with the Lord. These are the descendants of Noah. Noah was a righteous man and blameless in his generation..make yourself an ark of gopherwood..." (Gn 6:8-14)
"I will establish my covenant with you. You shall go into the ark, you and your sons, your wife and your sons' Of all living creatures you shall bring two of every kind into the ark..."(Gn 6:18-19)
