I am looking for a movie about some little girls that live with their mom they are poor and when something bad happens like there is a part where someone is banging on the door the mom tells them to pray but something goes wrong anyway and so the oldest girl stops believing in god then they get taken away by the state and they don't want to be separated and they finally find a couple who takes all of them and when the mom tries to visit them they don't want to see her anymore and they ask the couple if they can call them mom and dad
