There are many ways to help but I want to list several here:
Donate $10 to the Red Cross to be charged to your cell phone bill by texting “HAITI” to “90999.”
My church, the Evangelical Free Church in America has this portal for more information and a way to help.
I know there are many church groups who are reaching out. Commenters, if you hear of credible, reliable sources and initiatives, please post them.
And. Pray.
