The Gospels begin with both John the Baptist and Jesus teaching about the kingdom of God. Jesus told many parables about it.
The book of Acts begins with the risen Jesus teaching about the kingdom of God and ends with Paul in Rome teaching about it. Perhaps we should pursue and support the kingdom of God instead of human governments.
All Christ-followers need to surrender to God’s authority and yield to the signs of the kingdom of God, the fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. The kingdom is for now, not just for the future. Let the kingdom (government) of God come to you and be established as the authority over your life, as it is in Heaven.
Jesus said that some people can’t see the kingdom of God. Can you?
