Sojourning Under the Sun: Sabbath Reminder (2) (Genesis 11:1-9)

The Lord has washed the face of the earth with a flood, but has delivered a household through the ordeal waters of death.  Has sin been washed off the face of the earth?  We know that Ham mocked his dad and did not bear fruit of being one of the seed of the woman so clearly there are still sinners walking on the earth.  However, did man learn his lesson from the flood?  Did man get the message that God will carry out His justice?  Or does God need to intervene to restrain man? How can God intervene now that he bound himself to preserve this creation until the final Sabbath?
