"Jesus stopped and called them. "What do you want me to do for you?" he asked." (Matthew 20:32)
This seems to be one of the most obvious questions to ask a blind man from Jesus, then why should he even ask it in the first place?
The thing about it is this, people need to ask what they want because people in life don't know what they want.
We need to know what we want.
In life, we have this vague idea of what we want. We go about life having desires but not really crystalizing our desires into expressions of need.
It reminds me of the movie "Bruce Almighty" which in the end showed that most people don't know what they really want.
Some people want to be rich. But how rich? A person with a scooter in Bangladesh is quite rich. A person with a car in Singapore is rich, but a person with a car in LA would be the norm.
We must be specific in our needs and desires and have self-knowledge of ourselves. Only then can we set about concrete steps to get what we want.
