We are the temple of the Holy Spirit. When we praise, Jesus sits in the gateway to the temple (He is seated in the praises of His people). If we take the analogy of a gateway ( metaphorically our mouths as life and death are at the power of the tongue) this is the place of authority and access but also the place where business is conducted, declarations are made, oaths are taken and generally where things are “administered”.
The gateway is also a vector of expression, it is the place where we are “seen in public” as it were, where what we are in private is seen by all. With us humans this can be verbal, musical, artistic, mathematical, intellectual expressions but also actions or movement, work ethic, excellence kindness, love, joy, encouragement etc. Any godly expression that humans are capable of can be used to demonstrate the character of the King and thus of His kingdom.
When we are the temple of the Holy Spirit, we are the place where God is seated on His throne. The bible says that a river of life comes from the throne of God and flows out of the temple (Rev. 22:1) for, amongst other things, the healing of the nations.
When we praise, Jesus sits in the place of authority in our lives and administers the river of God flowing out of us to heal, cleanse, refresh, set people free, express God’s character and more broadly, bring heaven to earth. In effect, our expressions are literally becoming flesh because of our praise, we are releasing the power of life into the world to produce a tangible and results and change. Jesus is doing His Father’s business exactly in the place where a faithful Jewish son would have administered his father’s business 2000 years ago.
