In the beginning of the chapter, it talks about how God remembered about Noah and all the animals, the rain had stopped falling, and the type of things were visible after the water had dried off. Then, it talks about how Noah sent out a raven to fly back and forth to see if any water has dried off. Then Noah sent a dove to fly and find dry land, the dove came back with nothing from dry land, after 7 days, Noah sent the dove back, after it came back, it brought an olive leaf. Noah again, waited 7 more days and sent the dove to find dry land, it didnt come back. On the twenty seventh day of the second month the Earth was dry, and God told Noah that he can leave the boat and told him to release the animals. Noah built an altar to sacrifice burnt things. God smelled pleasant aromas and told Noah in his heart, that as long as there is anything living on the Earth, God wont destroy the Earth again. The lesson of chapter 8, is patience because Noah and everyone else on the boat had to wait until God told Noah that he can come out of the ark.
"But God remembered Noah and all the wild animals and the livestock that were with him in the ark, and he sent a wind over the earth, and the waters receded" (Gn 8:1).
“'Come out of the ark, you and your wife and your sons and their wives. Bring out every kind of living creature that is with you—the birds, the animals, and all the creatures that move along the ground—so they can multiply on the earth and be fruitful and increase in number on it'” (Gn 8:16-17).
"The Lord smelled the pleasing aroma and said in his heart: 'Never again will I curse the ground because of humans, even though every inclination of the human heart is evil from childhood. And never again will I destroy all living creatures, as I have done..." (Gn 8:21).
You need patience and faith for things to get better
