Is the kingdom of God only future or present also?

²⁰ But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, ²¹ who will transform our lowly body to be like his glorious body, by the power that enables him even to subject all things to himself. (Philippians 3:20-21 ESV)

That makes it clear that although citizens of the kingdom waiting above (since Christ the king waits above), we await on earth the kingdom coming “from”, heaven. The kingdom of heaven is to not “to heaven”, but from there, to earth.
