Revelation chapters 21 and 22 talk about New Jerusalem as the completion of God’s will. This is very important! Unfortunately, some mistaken it as a symbolic expression, and some think it only refers to the church. It states clearly in Hebrews 12: 22-24 that firstly, when we draw near to God or pray, we aim toward heaven, not inside of a person; secondly, New Jerusalem is a real city, because there will be the festal gathering with innumerable angels, the assembly of the firstborn—the church, and the spirits of the righteous made perfect, etc.
