"For the kingdom of heaven is like a landowner who went out early in the morning to hire workers for his vineyard.  He agreed to pay them a denarius  for the day and sent them into his vineyard... 
...Don't I have the right to do what I want with my own money? Or are you envious because I am generous?
So the last will be first, and the first will be last.
Matthew 20:1-2, 15-16 NIV
The disciples seemed to be stuck on the traditional power structures of their day, and that these would be reflected in the Kingdom Jesus was talking about.
And since they'd been there from the beginning, given their careers and lives up to follow Jesus, they figured that was worth something.
Deserved reward.
Jesus keeps reminding them that His Kingdom is based on radical grace.
Ridiculous grace.
I don't think they get that because they haven't seen the cross.
It's there that Grace gets real and blows away all their concerns about status & reward...
