I saw a comic a little while back that sparked this topic:

The message here is quite clear - anyone who says "thoughts and prayers" is doing nothing, or even worse than nothing. They are spouting their beliefs and not actually helping anyone. I see it all over "Stop with the thoughts and prayers - and actually DO SOMETHING!" It comes in various forms, but that is the message.
I'll start with what seems obvious to the faithful but may not be to others - when I pray for someone, I am literally asking an all powerful being I have complete faith in to intercede on their behalf. My ability to provide a concrete service may be limited, but God has no such limitations. I am using what I truly believe to be the greatest tool at my disposal. Sure, there are those who tweet or post it and aren't actually doing that - but assuming that's always the case is just another form of stereotyping.
The deeper issue here, however, is that it dismisses an entire group of people who - for all the reader of the tweet or post knows - ARE doing something to help. After I posted it regarding the hurricanes, I donated to relief efforts, as did many. People prayed for the victims, then stepped out to rescue them in boats. Sent water. Sent food. Opened their businesses and gave out food for free to keep them going. People who weren't in a position to directly help tried to impact the world around them in other ways to demonstrate care for others - stopping to help someone with a flat tire, paying for the coffee of the person behind them, or providing a homeless man with a jacket. Seeing "thoughts and prayers" and immediately blasting the person for not doing anything is like assuming everyone who tweets about loving Pepsi is drawing up plans to bomb a Coke factory. Prayers and action are not by any stretch of the imagination mutually exclusive.
And don't for a second think I'm letting us off the hook, fellow faithful. I want you to think about the last time you said "thoughts and prayers." Did you actually pray for the person or situation? Did you truly, with your heart in it, as God to help?
Even less comfortably, did you keep your heart open to listen to see if God wanted you to be part of the answer to that prayer? Because here's the thing - God uses people to answer prayers. When my daughter needed surgery, He used surgeons, nurses, parents of other kids with CHDs, and numerous others to help her and me. When a flood comes, He uses people with boats, people who donate, people who can step in and re-build. When a shooting occurs, He uses first responders, clergy, neighbors, therapists.
Prayer is powerful, but we need to be sure we aren't just paying lip service. That's what leaves the door open for others to say we are wasting our breath. And if there's anyone reading this who isn't among the faithful, please don't jump to conclusions. We are acting on our full faith in a higher power, and are also working in ways you can't see from a single tweet or post.
