I’m really not certain about the difference between the Kingdoms. Jesus said that the Kingdom of Heaven comes from within and is spread upon the face of the earth. Because of that saying, I assume that we’re already living in the Kingdom of Heaven, we just have to let it out from our hearts. But he seems to have spoken of the Kingdom of God as being totally separate from the Kingdom of Heaven that we have in our hearts. I don’t know what more I can glean about those differences so I simply try to live as Jesus taught and hope for the best on Judgment Day.

Thank you for your reply, there really is much to consider and I may never learn it all in this life.
