There are many ways to help including the following 3 options.
The Red Cross
First, one of the easiest ways to help is through the Red Cross. In the USA you can text “Red Cross” to 90999 and $10 will be automatically charged to your phone bill as a donation.
If you have an iTunes account you can easily make a donation that way as well.
Finally, no matter if you are able to donate financially, please pray for the men, women, and children of Japan.
