I used to do this for my Aunt Gladys. I’d be on the way back from taking her to a doctor appt and she’d be sitting there with TV face in another world. So I’d just start singing the old hymns. After a while she would start to sing quietly then louder, then in harmony. After driving around for awhile in worship therapy we ended up in the Taco Bell drive up because she was hungry. Then she’d tell me the old stories of her family when her dad led the church and her mom played the piano. Worship therapy, that’s what is. Able to reach us when nothing else can.
