God saw how corrupt the earth had become, for all the people on earth had corrupted their ways
We who believe that God made the heavens and the earth,know that God does not play. That his promises are worthy. When God told Noah to build his ark, Noah asked God why and the how to. God explained. Though it took all of his life, Noah was obedient. Which lead to his life and the life of other beings survival. What if God asked you to do something in preparation of an event or events? Would you be faithful & obedient?
