The ambition to build a city with a tower that reaches to the heavens reveals the desire in the adamic personality to join with others in order to accomplish something of significance, the idea being that we can gain a name for ourselves. Also, we can achieve power that we would not have were we to be a single individual or a small group of people. By combining our efforts, our wisdom, and our talents we can establish a monument on the earth to our own glory.
However, God often works through intense interaction with one person, such as Moses, Elijah, John the Baptist, or the Apostle Paul.
