““In “The Cost of Discipleship” Dietrich Bonhoeffer makes it clear that grace is free, but it is not cheap. The grace of God is unearned and unearnable, but if we ever expect to grow in grace, we must pay the price of a consciously chosen course of action which involves both individual and group life. Spiritual growth is the purpose of the Disciplines. It might be helpful to visualize what we have been discussing. Picture a long, narrow ridge with a sheer drop-off on either side. The chasm to the right is the way of moral bankruptcy through human strivings for righteousness. Historically this has been called the heresy of moralism. The chasm to the left is moral bankruptcy through the absence of human strivings. This has been called the heresy of antinomianism. On the ridge there is a path, the Disciplines of the spiritual life. This path leads to the inner transformation and healing for which we seek. We must never veer off to the right or to the left, but stay on the path. The path is fraught with severe difficulties, but also with incredible joys. As we travel on this path the blessing of God will come upon us and reconstruct us into the image of Jesus Christ. We must always remember that the path does not produce the change; it only places us where the change can occur.””
