The covenant with Noah was a terrifying precursor to Pentecost, an outpouring of divine anointing previously unmatched in the history of the human race. In its wake, Noah’s children and grandchildren walked as gods among men, outliving their great-great-great grandchildren and ruling as no one has since. The great river valley civilizations were born overnight, deliberately created from whole cloth by men and women divinely commissioned to build human culture from the ground up.
