In the book of Daniel we read about the dream of King Nebuchadnezzar. He saw a statue with a head of Gold, a shoulder of silver, a middle of bronze and lower parts of iron, and iron with clay. These were the kingdoms of the world at that time, and to come. Then a rock struck that statue and shattered it, and then grew to fill the whole world. That rock is a symbol of the Kingdom of God.
The Kingdom of God is not some vague reality that never impacts the world. Rather it is to have great impact, so that it shatters this world's kingdoms completely. Jesus taught his disciples to pray “Let thy kingdom come, let thy will be done on earth, as it is in Heaven.” (Matt 6:10) The Kingdom of God is supposed to have an impact in the world here, now, and increasingly until it has filled the whole world. The gospel is supposed to have power and to change things, permanently.
And so God is restoring apostles, restoring their authority, and restoring proper relationships in the Body of Christ. The kingdom of God is here, and it is coming too, with great power.
