First and Last

"The first will be last and the last will be first."  There are so many ways this can apply to us.  Who is the first?  Who is the last?  Will they just be made equal?  Will their positions be reversed?  What does that mean for us who believe?  Do you think about where you might fall in a kingdom hierarchy, or are you satisfied that you're "in," that you're saved?  Might be good to give Jesus a listen here....  From Matthew 19:27 - 20:16.
