Few people have the type of experience you describe so it cannot be depended on as an antidote to people leaving formal religion..  

My question to you is about your understanding of  the result of Christ's call.  You seem to imply, and I may be wrong, that Christ's call inevitably leads to church membership, perhaps in your mind, to Catholic church membership. I am not sure if you are Catholic or not.

Another view is that God calls us, that we are all on a spiritual journey, seeking God, even without knowing it at times.   Each path may be different, as designed for each person. So some may, like your daughter, sit in a church to talk with God. Others may sit on a riverbank and do the same thing.
