Wow .. deep question.  I suppose I would have the usual questions like why did my brother die when he did.  Maybe ask if he could enlighten me about the lessons he wanted me to learn from a few incidents in my life.  Mostly because they keep coming back around and I figure I didn't get it right the first time.  I think though that he knows my heart and I have already asked him these things in prayer.. just haven't had the answers yet.  Asside from the questions I would thank him for the family I grew up in and all the people that have touched my life.. good and bad.  I'd be curious about what is ahead but I know he can't tell us any more than we already have been told in the Bible.  I'd be curious about what he finds amusing and how he relaxes.  Is there a particular place on this earth that he feels is really more beautiful than the others"  Just general conversation I suppose. 

When we accept Chirst into our lives by the power of the Holy Spirit he moves into our hearts.  So in that respect the kingdom of God is inside each of us.  When I read scripture such as these I consider that my brothers and sisters in Christ are all carrying Christ in them as well and is therefore among us at the same time.  as it says "whenever two or more are gathered in my name there I will be also." 

And yet I also know that satan is prince of this earthly world until Christ returns.  So Yes I do believe the "kingdom has come near" but if you are saying that this (this life we are living out on earth) is heaven I would have issue with that.
