Family Life has a good article about 10 ways to minister to orphans. I really liked their first suggestion. But I was dissapointed that FOVC didn't make their top 10... apparently they just don't know about FOVC yet.
James 1:27 [the bible] does tell us to care for the orphans and the widows. Check out this article (or the FOVC website) to see what you can be doing to follow God's command.
