Always insist that the focus be your relationship with God, the with-God life that we’re after, and not on how to master one practice or another. One practice might help this individual; another practice is what will help that individual. We learn the heart of the person, and spiritual Disciplines appropriate for the individual will flow out of this life together. We don’t try to nail any of this down too tight. In my opinion, it is futile to try to measure this or that. We can know that a person is growing spiritually when they are more loving. That’s how we know.
