This first reflection is how God is in the city, here’s the Pslam:
1 Great is the Lord, and most worthy of praise, in the city of our God, his holy mountain.
2 Beautiful in its loftiness, the joy of the whole earth, like the heights of Zaphon is Mount Zion, the city of the Great King. 3 God is in her citadels; he has shown himself to be her fortress.
4 When the kings joined forces, when they advanced together, 5 they saw her and were astounded; they fled in terror. 6 Trembling seized them there, pain like that of a woman in labour. 7 You destroyed them like ships of Tarshish shattered by an east wind.
8 As we have heard,so we have seen in the city of the Lord Almighty, in the city of our God: God makes her secure for ever.
9 Within your temple, O God, we meditate on your unfailing love. 10 Like your name, O God, your praise reaches to the ends of the earth; your right hand is filled with righteousness. 11 Mount Zion rejoices, the villages of Judah are glad because of your judgments.
12 Walk about Zion, go round her, count her towers, 13 consider well her ramparts, view her citadels, that you may tell of them to the next generation.
14 For this God is our God for ever and ever; he will be our guide even to the end.
Verses 1-3 talk about the God in the city, that he dwells in its centre he is found with in it’s walls. This is in the context of surrounding Pslam’s including 46:
4 There is a river whose streams make glad the city of God, the holy place where the Most High dwells. Psalm 46
