I am going to put an end to all people
When God created human kind in Gen 1 he commanded them to be fruitful and to fill the earth. Made in the image of God they were to populate the world with the image of God, instead, because of their sin, the scriptures say:
Now the earth was corrupt in God’s sight and was full of violence. 12 God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. It grieved God so deeply that he had made something that had become so corrupted by sin that he decided to put an end to it all.
The means he chose was a FLOOD in which all flesh would be destroyed, he says (:13). But God is caught in this desperate love affair. He hates what has become of his creation, but he cannot bear to let it go completely, so he selects the one righteous man and his family and makes a way of escape for them and the animals. He commanded Noah to build an ark, into which he would secrete Noah’s family and two of every unclean animal and seven of the clean animals.
Despite the bizarre nature of the command, Noah obeys.
The story of God’s saving grace is interwoven with the story of Noah’s obedience. This is our part in fellowship with God. Trust and dependence on God’s saving power must be married to daily, visible obedience. An obedience that is not just true of us when we are in church, but in the daily grind of bearing the hammer and the nail and the pitch, constructing our metaphorical arks. The scriptures say:Genesis 6:22 Noah did everything just as God commanded him. Also 3:5.
Chapter 7:8,9 have this wonderful picture of all the living creatures of the earth making a mass pilgrimage to that only place on the planet where salvation was to be found, in the ark. Even as the rain began, animals and humans are making their way that journey.
