PSALM FORTY-EIGHT ,WHERE GOD IS

Psalm 48:3 NIV   God is in her citadels, he has shown himself to be her fortress.
                  TLT   God himself is in Jerusalem's towers
                            he reveals himself as her defender.
              NASB    God , in her palaces has made Himself known as a stronghold.

Psalm 48 is about wanting to be where God is, in the comfort of His presence within the city wall.

Until recently most people walked !
We walked into battle and then walked home again. We walked on pilgrimages.
Large events were attended by people who walked there.
Refugees have walked in China and in Russia. Many have walked across much of the African continent
to reach Europe.
Walking  people carry only what they can manage and when they get to where they are going,
people make themselves comfortable in a sheltered space.
Generation after generation of God's people can sing with the psalmist ;-
Psalm 48:8 (New RSV)
                                    As we have heard, so we have seen
                                    in the city of the LORD of hosts
                                    in the city of our God
                                    which God establishes forever.

The city walls of Jerusalem encompassed not only a sheltered space but also a sacred space.
