I often say a prayer for strangers. Whenever I see or hear an ambulance passing by, or when I see someone disabled on the road. I also say a prayer when I see someone stoned and falling or talking to themselves on the streets. There is an app called 'LWL', which means life without limbs. This was created by Nick Vujicic. People submit prayer requests on this app. It is a wonderful app where people say prayers for each other. We never know and it might actually work when we say a prayer for someone.
