Question

The Holy Spirit is the third person of the Trinity. He is everywhere and exercises all the awesome power of God.

In contrast Jesus is constrained by the physical limitations of being human. Even though he has a spiritual body and can move between the physical and spiritual worlds, he can only be one place at a time. He could not raise himself from the dead, but needed to be raised by the power of the Holy Spirit.

Here is my question: If the Holy Spirit, who is all powerful cannot bring in the Kingdom of God, how would Jesus be able to do it when he returns?

I suppose that he could get his followers to kill everyone who opposes him, but that would not be a very nice kingdom. It would be quite different from the Kingdom that he promised.
