J. I. Packer on the importance of cultivating the inward disciplines of the Christian faith and not focusing solely on outward performance (from his book, Keep in Step with the Spirit: Finding Fullness in Our Walk with God):
The journey of our lives is a double journey. There is an outward journey into external confrontations, discoveries, and relationships, and there is an inner journey into self-knowledge and the discovery of what for me as an individual constitutes self-expression, self-fulfillment, freedom, and contentment within. For the Christian, the outward journey takes the form of learning to relate positively and purposefully to the world and other people–that is, to all God’s creatures–for God the Creator’s sake, and the inward journey takes the form of gaining and deepening our acquaintance with God the Father and with Jesus the Son, through the mighty agency of the Holy Spirit.
Now in the hustling, bustling West today, life has become radically unbalanced, with education, business interests, the media, the knowledge explosion, and our go-getting community ethos all uniting to send folk off on the outward journey as fast as they can go and with that to distract them from ever bothering about its inward counterpart. In Western Christianity the story is the same, so that most of us without realizing it are nowadays unbalanced activists, conforming most unhappily in this respect to the world around us. Like the Pharisees, who were also great activists (see Matt. 23:15!), we are found to be harsh and legalistic, living busy, complacent lives of conforming to convention and caring much more, as it seems, for programs than for people. When we accuse businessmen of selling their souls to their firms and sacrificing their integrity on the altars of their organizations, it is the pot calling the kettle black. Perhaps there are no truths about the Spirit that Christian people urgently need to learn today than those that relate to the inner life of fellowship with God, that life which I call the inward journey. (You could also call it the upward journey–that adjective would fit equally well.)
