Naos is from the Greek word nāós dwelling of a God, inner part of a temple, or shrine. The ancient Israelite temple was a symbol that pointed to God's desire to live among his human partners and rule the world through them. The temple was a sacred place to the ancient Israelites. The temple is a place where Heaven and Earth are united. As Moses led the people out of Egypt, God commanded the people to build the Tabernacle. This tent structure served as a place for God to dwell with his people (Exodus 25:8 ... 'Let them construct a sanctuary for Me, that I may dwell among them.').
The New Testament writers continue to use temple language, but they are no longer concerned with a building. Incredibly, when they write about the temple, they talk about the people of God! The apostle Paul writes, “Do you not know that your body is a Temple of the Holy Spirit within you” (1 Corinthians 6:19-20).
