ISB ~ Revelation 21 v22

its temple is the Lord:The Trinity is the sanctuary of the heavenly city, which is encompassed by the Father (Lord) and the Son (Lamb) and filled with the glory of the Spirit (light). If the old Jerusalem was built around the Temple, the new Jerusalem stands within a Temple, and one that no longer has partitions or veils to prevent access. In theological terms, this means that communion with God in heaven will be unmedi-ated, exceeding in closeness and directness the access to God’s presence once enjoyed in the sanctuary of Israel.
