Here's something clever.    

Compassion International is arranging a trip for a few good bloggers to Uganda to see their work firsthand. Read about their trip here. Why bloggers? Well, a firsthand account can be far more compelling than an ad in a magazine or a plug on a radio station.  

Here's the info, hopefully "clickable":

We've sponsored a child through Compassion through her "graduation", and it was a blessing. The hand-written notes and correspondence are touching. Our child was from Guatemala, and allowed us, in a small way, to expand our understanding of the scope of the Kingdom of God.

If you've never thought about sponsoring a child, spend a few minutes investigating the idea.
