Without wonder we approach life as a self-help project. We employ techniques, we analyze gifts and potentialities, we set goals and asses progress. Spiritual formation is reduced to cosmetics.
If there is no Sabbath--no regular commanded not working, not talking--we soon become totally absorbed in what we are doing and saying, and God's work is either forgotten or marginalized.
(Through Sabbath) Our souls are formed by what we cannot work up or take charge of: We respond and enter into what the resurrection of Jesus continues to do on the foundations of creation, our work, and workplace.
