No matter how mentally tough we think we can be, our brain is never going to reject permanently its own natural selfishness and willful tendencies. This natural resistance explains why indulgent habits and addictions and moral failings are so difficult to overcome in any permanent way.
It also explains why Christ healing is more about surrender than mental toughness—more about yielding than self-discipline. Such surrender, as CS Lewis wrote, must begin as soon as we awake each morning. When our “wishes and hopes for the day” come at us “like wild animals,” our task “consists simply in shoving them all back; in listening to that other voice, taking that other point of view, letting that other larger, stronger, quieter life come flowing in” (Mere Christianity 154).
How comforting and helpful these words have been for me! When spiritual healing has occurred in my life, in physical and moral ways, the change took place only as I yielded, as I let Christ’s “larger, stronger, quieter life” win the day, the hour, and the moment. Spiritual healing and regeneration is not about mind over matter but about Christ over all!
