The Christian community is interested in spirituality because it is interested in living. We give careful attention to spirituality because we know, from long experience, how easy it is to get interested in ideas of God and projects for God and gradually lose interest in God alive, deadening our lives with the ideas and the projects. This happens a lot. Because the ideas and projects have the name of God attached to them, it is easy to assume that we are involved with God. It is the devil’s work to get us worked up thinking and acting for God and then subtly detach us from a relational obedience and adoration of God, substituting our selves, our godlike egos, in the place originally occupied by God.
