Our hearts ache for the people of Haiti. Orphans are highlighted now more than ever. Romans 8:28 says "And we know that in ALL THINGS God works for the good of those who love him, who have been called according to his purpose." Good can come from calamity. But would adopting a child from Haiti be prudent at this time of crisis? Please read these two posts (from Sarah who is an advocate for Children's HopeChest and Gina who works for World Orphans) that describe both the tug to "save a life" and the need to WAIT. Biological families need to be found and reunited. That might take time.
Pray for God's leading in this matter, and in the meantime, find a place to help the people of Haiti. The above posts mention a few places. Samaritan's Purse is another organization that has been working hard in immediate, tangible ways since the day of the earthquake.
Remember...microgiving can make a MACRO difference!
