The Psalms have many prophecies and shadows of Christ, God’s house and city, and their blessings to the whole earth. All of these point to Christ in New Jerusalem on the new earth.
Psalm 122:1-3 says,
I rejoiced when they said to me, let us go __to the house of Jehovah.
Our feet are standing within your gates, __O Jerusalem.
Jerusalem has been built as a city that __has been compacted together.
The present reality of the house of God is the church (1 Tim. 3:15). Let us go with rejoicing to this house to enjoy Christ with all the believers. When we do this we are standing within the gates of God’s spiritual city. All of this is our foretaste of New Jerusalem. And, as Jerusalem was built, so the church now is being built now (e.g. Eph. 4:16, 1 Peter 2:5) as a forerunner of the builded New Jerusalem.
Psalm 132:13-14 says,
For Jehovah has chosen Zion; He has desired it for His habitation.
This is My resting place forever; here will I dwell, for I have desired it.
God has chosen Zion and we too should choose to long for God’s house and city. New Jerusalem will be consummation of both, where God and we also will dwell eternally.
Verses 15-16 say,
I will abundantly bless its provision; I will satisfy its poor with bread.
And its priests I will clothe with salvation, and its faithful ones will shout with a ringing shout.
Today the promise of abundant provision is fulfilled by the flow out from the Head, Christ (Col. 2:19) and the Spirit poured upon us richly (Titus 3:6). How much more in New Jerusalem with the river of life and tree of life! We participate in God’s salvation and shout for joy now with more in New Jerusalem.
