If God created the universe in a particular fashion, and if sin has marred what He has created, then humanity is no longer in its proper form. We're distorted, not what we're supposed to be. Part of spiritual formation, then, is an attempt to return to that original state, to find our way back, or better, be led back, to what we were made to be.
With the rise of psychological thought, the language of psychological or emotional health has made its way into our conversations. We occasionally talk about making healthy choices or being emotionally unhealthy. There is an implied desire (and why shouldn't there be?) to move towards health. I believe that this move towards health is a move towards our original design. To be unhealthy is a way of not being what we're supposed to be, and what we are supposed to be is therefore healthy.
And I think this may transcend categorization. There is psychological or emotional or mental health. There is also physical health. There is surely spiritual health as well. If part of our being is psychological, another part physical, another part spiritual, etc., then the redemption of all of these parts is a movement towards positive spiritual formation. To be spiritually formed is to be restored towards an ideal state in all its facets, to become healthier. Conversely, if we are becoming healthier in any of these facets, then we are being spiritual formed; it is part of spiritual formation.
Now let me back way, way up before it starts looking too much like I’m speaking negatively of spiritual disciplines. They are unquestionably helpful, meaningful, and likely beneficial tools in the process of growth and formation. They help us to make room for God and the spiritual life, may open us up to the truth of ourselves and God, and can help train our bodies to engage with life in more positive manners and help to eliminate unhelpful habits. These are all undeniable positives. Thus, I heartily recommend spiritual disciplines of many sorts.
I know that nothing can separate me from the love of God, but what about being separated from the experience of that love? My own unwillingness to enter into that love, my capacity to distract myself or to be distracted, some deep-seated and unconscious expectation that God isn’t really there, all of these things and plenty more can get in the way of my experience of the love of God. And that’s disheartening. While I’m not diminishing God or His love, I am losing an experience of it, which means how it affects me. That’s quite a loss. I don’t intend to get in the way of experiencing God, but I do, despite my best efforts.
