In fact it may be entirely too concrete for some of us. If you feel that religion should have nothing to do with politics, I advise you to stay away from this petition. We are praying that God's sovereignty may come to earth and become effective in the political realm and for the political questions that plague us and at times divide us. Not like any of the kingdoms we see in our day. Jesus tried to paint us a picture.
Some differences come to mind immediately.
For example, in an earthly kingdom, rank is determined by who happens to be the most powerful - the princes and nobles are the most wealthy and strong. But, according to Jesus, in God's kingdom rank is determined, not by how powerful you are, but by how much of a servant you are. He said that only those with a childlike attitude, one of faith and trust, are able to be a part of it. God's kingdom is different. But Jesus described God's kingdom as a great banquet with folks coming from North and South, East and West.
