If prayers worked I would pray for your healing. I really truly would. I would spend every waking minute prostrating myself and doing whatever it took to get the almighty to intervene and make right whatever's wrong with you or your spouse or your child or your relative or friend.
But prayers don't work like that. So instead I'll work for more fair and equitable healthcare, to help get you access to doctors and hospitals and medicines who actually can heal you when you need them. That seems like a better use of our time here on earth, so I hope you'll accept that instead of prayer. It turns out to be a lot more work.
