The next thing that Genesis teaches us is that people think that they can become like God.  The people decided that they would build a tower to reach God so that they could be like God.  There are stull many people today who deny the existence of God because they believe that they are too smart to believe in His existence.  Some people do not really want to become like God, but they feel that they are even greater than God.  As we see in Genesis, this is nothing new.  God proved them wrong then, and He will prove them wrong now.  Of course, there is little danger in the people of the world being united in one purpose today.  Then, when the world became too evil, God destroyed nearly all of mankind, except for Noah and his family.  We may live in an evil world, but it isn't the first time the world has been evil.  Of course, the next time God destroys the world it will be time for His everlasting judgement.  As followers of Christ, we have a command to reach the lost with God's message of salvation, and we may be the only ones standing between mankind and God's judgment.  If the time comes when no one responds to God's gift of salvation, then there will be no reason to delay the coming judgment.  I believe that instead of looking for the signs of the coming judgment, we need to be reaching out to the lost world.  There is never a time that we as followers of Christ should ever live simply waiting for Christ's return so that the evil people of the world will get what they deserve, because without forgiveness through our faith in Christ we deserve the same punishment that any lost sinner deserves..  Our commission is to reach them with God's love and message of salvation.
