You do not know what you are asking -- Matthew 20

Matt20:22"You do not know what you are asking."
This is an interesting verse. So many times we pray for something, but we really don't know what we're asking. I remember a friend told me that she prayed fervantly that God will use her as David. Then later she found out that the temptation she faced to fall into sexual sin was tremendous. She didn't realise that God answered her prayer in a whole package deal.
Everything's got a price. If we want a new car we've got to pay for it. If we want a beachfront new house (in Sydney) then that's gonna cost us quite a bit. We'll pretty much have to change our lifestyle if we want to make that much money. If we want big blessings, do we really want to pay for that price and change our lifestyle a whole lot?
