$5 and $10 donations are easy to make, and they really add up. It's a terrific way to include vastly more donors. It's not just that people have cell phones and the phone company already has all your credit card information, it's that it makes small cup-of-coffee size donations the norm.
Text the word "HAITI" to 90999 to donate $10 to the American Red Cross. And get on with your life!
Now, maybe you think charity should involve more reflection and attention to the object of charity. Maybe you think charitable donors should feel that they are giving something up for the sake of the less fortunate and be personally transformed by the act of giving. You know how people who make the effort to attend a long church service feel about the people who say, "I can pray anywhere!," "I can pray on the golf course," "I'll pray when I'm stuck waiting in line somewhere," etc.
Jesus said: "But when you give to the needy, do not let your left hand know what your right hand is doing." So do not let your left thumb know what your right thumb is doing. Text some charity and don't make any kind of deal out of it. Don't even let yourself think that you have done anything. There is good in that, and it's a good instantly achieved by everyone with a cell phone. You're only giving $5 or $10, so there isn't even anything to congratulate yourself about. When everyone just does this, without thinking, the charities get millions, and we have no reason to get puffed up about about our benevolence.
