You remind me that I need a new prayer list. It's in my old phone. I generally have a list of 15-20 people and some families. But I just use the app on my phone, the old phone had One Note, the new one has Samsung Note or something like that. After you enter a couple of people in there you then will come to organize it. I've done church intros using that method as well. You will think of ways to lay it out.
Some prayers are so simple " your will be done Lord but if you would consider this +++++". There are all types of prayer, sometimes healing, sometimes speaking for non believers ( I've had good success with this). And for families of deceased. And don't forget yourself. Prayers don't have to be long and involved, He reads our hearts and minds anyway, but the act of coming to Him is often enough.
