Check out this brief post from The Haiti Orphan Project titled: Orphans. And Us.
These are important things to consider and act upon. Caring for orphans is about transformation, not just for them but also for us. God uses us to minister to others but he absolutely ministers and molds and shapes us when he is using us in this way. We don't grow much by reading books, although reading books is valuable. We grow most when we get out hands dirty and when we open our hearts to others.
I would encourage you to seek out a way to get involved in orphan ministry. There are few ministries that get to the heart of the Gospel quite like this one.
