What are the psychological benefits of prayer?

Prayer can foster a sense of connection, whether it's to a higher power, what a person finds important in life or their values, said Ryan Bremner, an associate professor of psychology at the University of St. Thomas in Minnesota. Prayer can reduce feelings of isolation, anxiety and fear as well.
Does prayer actually change God's mind?
Our thoughts about God, our feelings toward our neighbour's, and the state of our heart all change when we pray to God. In addition to prayer changing us, prayer does change things around us. As Sproul states: The mind of God does not change for God does not change.
