The second half of Revelation 21 tells us more about the bride of Christ. The bride is the city. The description of the city tells us the glorious clarity of the saints in the heavenly city allows the God's glory to shine through all who are there. We will be worshiping in the very presence of Jesus. Nothing will hurt or destroy in all His holy mountain which is the heavenly kingdom. Everything there is described as being golden which represents the complete holiness of God.
