Some friends of ours in California are heavily involved with Compassion International, a non-profit Christian organization that helps make life better for children around the world. One country where they work is Haiti.
If you would like to help the relief efforts in Haiti, Compassion International can provide that venue for you! You can go to Compassion's Earthquake Response page to learn how to contribute directly through them if you would like.
For updates on the relief work and specific ways to pray, you can visit Compassion's page here where they are posting updates.
If you are in the States, you can also text "disaster" to 90999 to give $10 to Haiti relief funds. I believe this is going through the Red Cross.
Thank you for your prayers! May God be glorified!
