Psalm 87 like Psalm 84 is a Psalm that focuses on the city of God. Part of this finds its fulfillment in the physical city of Jerusalem, as this psalm would have been sung at the temple during feasts. However, as we read through this Psalm we see that it draws out eyes toward eternity. In the City of God we see a description of many different nations and they are described as being born there. Jesus tells Nicodemus, and us, that if one wishes to enter the Kingdom of God then he must be born again. And this Psalm foreshadows the idea that Jesus taught.
