“Jerusalem--built as a city that is bound firmly together” (v3). The psalmist sang of a Jerusalem that was a holy idea as much as a place. Jerusalem with its Temple was created to be the center of God’s presence among His united people, yet in reality the nation experienced rebellion, civil war, and conquest. However, Jerusalem/Zion always symbolized their hopes: for peace and security, for unity, for God’s kingdom (“thrones of judgment”) to be established on the earth (v7-9).
“Let us go to the house of the Lord!” (v1). Human effort can’t build God’s kingdom, so Jesus came to be Immanuel, God among us, opening the promises of Jerusalem to the whole world.
