He blotted out every living thing that was on the face of the ground … Only Noah was left, and those who were with him in the ark (Genesis 7:23). The worldwide Flood is sobering to consider. In Noah’s day, at a real point in time in actual history, every person on earth was drowned except the eight who were in the Ark. This is the greatest catastrophe in history, and no other event — tsunami, earthquake, hurricane, or volcanic eruption — even comes close. This was not a “natural” or normal kind of catastrophe.
Then they said, “Come, let us build ourselves a city and a tower with its top in the heavens, and let us make a name for ourselves, lest we be dispersed over the face of the whole earth” (Genesis 11:4). The great sin of the city of Babel is not tower-building, or unified labor toward a societal goal. The sin of Babel is the sin of seeking independence from God.
Make yourself an ark of gopher wood. Make rooms in the ark, and cover it inside and out with pitch. This is how you are to make it: the length of the ark 300 cubits, its breadth 50 cubits, and its height 30 cubits (Genesis 6:14-15). The Big Boat The dimensions of the ark were about 450 feet long, by 75 feet wide, by 45 feet high. Such a huge vessel would have had a total storage capacity of almost one and a half million square feet.
Whoever sheds the blood of man, by man shall his blood be shed, for God made man in his own image. And you, be fruitful and multiply, increase greatly on the earth and multiply in it (Genesis 9:6-7). God knows that humans are fallen, broken creatures. Even as Noah steps off the Ark into the new, post-Flood world, God is already addressing the issue of homicide.
