The Kingdom of Heaven

Matthew 18:1 At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven?

Yes, I know I didn't come back yesterday, but I'm here today and I have some more questions to ask. You may be thinking that the reason that I am writing here is to tell everybody what the bible says, and I want to remind you my purpose is to show you the value of reading the bible for yourself.

As I was re-reading, I was paying attention to a few things here and "the kingdom of heaven" is one of them. Well... it just so happens that that phrase is used 33 times in the book of Matthew so the question they are asking is good one to ask Jesus to clarify.
The next question I have to ask is where is the kingdom of God? For all of my Christian life I have assumed that the kingdom of heaven is some future place and some future event. I believe that I have been wrong in that assumption because all the examples Jesus is laying out in the rest of this chapter are situations that happen here and now among us as human beings. Further more Jesus differentiates between "the kingdom of heaven" and "in heaven." as he is answering their question.
So I will now re-read this section again, only this time with the understanding that the kingdom of heaven is here and now and within me and see how it fits.
