And there came unto me one of the seven angels
and shewed me that great city, the holy Jerusalem,
 Having the glory of God:
even like a jasper stone, clear as crystal;
 And had a wall great and high, and had twelve gates,
and names written thereon,
 On the east three gates; on the north three gates;
on the south three gates; and on the west three gates.
 And the wall of the city had twelve foundations,
and in them the names of the twelve apostles of the Lamb.

I. The Holy City is a walled City.
 And had a wall great and high... And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.  And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.  And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.  And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass.
1. The Walls of the City of God
What purpose do walls serve?
Security - walls provide a barrier between you and the enemy
There is exclusion. (John F. Walvoord - “an obvious symbol of exclusion”?!?!)
“The mention of a wall is not to suggest the necessity of security precautions in the eternal state....The wall is simply part of the description of an ideal city as conceived by ancient peoples accustomed to the security of strong outer walls.”
“On the gates of the city are the names of the twelve tribes of Israel, and on the foundations the names of the twelve apostles. Just as Paul’s use of the olive tree symbolizes the joining of Jew and Gentile in the plan of God, so John’s use of the one wall around the holy city (21:12) illustrates the oneness of the people of God in its highest and most spiritual sense.”
