Parable of the Unjust Steward: Mystery solved?

Chaplain Mike rules the day again!

Has anyone ever read the Parable of the Unjust Steward?

Just a few months ago, I was struggling with interpreting this very same parable. I just didn't make sense - Why would any boss praise his subordinate for giving away his money??

So today, when I was catching up with Chaplain Mike's older posts, I saw his take (or rather, C. Blomberg, Interpreting the Parables, p. 224) on it:

The subordinate goes to each of his boss’s debtors and writes off his own commission from what they owe. In so doing, “his master was not out any money rightfully his, the servant himself absorbed the loss, amends for previous wastage were partially made, and the man gained new friends who would care for him after his firing”

It's a pretty brilliant explanation, but I'm still not totally convinced. Thoughts, anyone?

Here's the audio bible version of the parable for you to listen, if you like :P
