what do I need to bring with me?

This morning I was looking at some internship information for an organization that serves the poor (including living among them). And I came across this:

All interns are considered self-supporting missionaries. This means that you must find a job to support yourself. However, you will need to bring a total of $3,500 with you to Orientation.
That's not surprising; it's pretty standard for internships like this one. But it stands in stark contrast to the call of Jesus I mentioned in my last entry:
"Sell all that you have and distribute to the poor, and you will have treasure in heaven; and come, follow me." (Lk 18.22)
