The Now, and the Not yet
The Kingdom of God is King Jesus’ rule and reign over us. It is not a place; it is a state of being. God does not intend for us to wait until we are dead in order to experience eternal life, Jesus has always been intent on bringing heaven to earth beginning now.
The phrase ‘now and not yet’ expresses a certain way of thinking about the Kingdom of God – it is here now, but it currently coexists with Satan’s Kingdom, however, it will soon exist entirely on its own. The kingdom of God has come and is coming in fullness. When we see miracles we see God’s kingdom reign breaking into our world.
Your kingdom come, your will be done, on earth as it is in heaven.
Matthew 6:10 (ESV)
