Psalm 122 begins with an expression of gratitude to be able to go into Jerusalem. We modern day Christians can read this as a reminder of what God did long ago, and we can read these words as a reminder of what God is still doing and will do.
What is our Jerusalem? Where do we see ourselves gathered in worship? Do we visualize this place as one with many kinds of people gathering?
And, there, what do we pray for?
And, having prayed, what do we do when we leave our places of worship? Whose good are we seeking?
