Messiah has called us to set forth His Kingdom.  We are to announce it.  We are to seek its advancement among the peoples of the earth.  The church is to reflect what it looks like.  When the church seeks to be honored at the table of Constantine, it wanders aside from its own message.  The emperor is not Lord!  Jesus is Lord!  We discover the Kingdom at the table of the Lord, which is the banquet to which all nations are invited.

And He said to another, “Follow Me.” But he said, “Lord, permit me first to go and bury my father.”  But He said to him, “Allow the dead to bury their own dead; but as for you, go and proclaim everywhere the kingdom of God.” Luke 9:59-60 (NASB)
