I recently read two articles by a well-known Christian author who is also closely connected to a Christian counseling foundation. The articles essentially argued that mental illness was a social construct created by secular doctors and psychiatrists, and therefore is not biblical.
So, when a person is depressed, he is really just experiencing sadness, and to try to treat it medically is to short circuit the power of God. When a person is anxious, she is really just experiencing worry, and to treat it medically is a secular answer to a spiritual problem.
You get the idea.
The desire behind the article was good: The author was trying to demonstrate that Jesus is sufficient for every facet of life. However, I believe that treating mental illness as only (or even primarily) a spiritual problem is both profoundly unbiblical and incredibly hurtful to those who struggle with mental illness.
Total depravity really means total depravity.
The Bible teaches that every human being is totally depraved. This doesn’t mean that every person is as absolutely wicked and evil as they could possibly be. That would be utter depravity.
Total depravity simply means that sin has affected every facet of my being, including both my soul and my body.
Total depravity means that nothing works as God originally intended. My spiritual desires are affected and distorted by sin. My intellect is distorted by and affected by sin.
And, most importantly (for this discussion), my body has been affected and distorted by sin.
Why do I get colds and headaches and backaches and indigestion and infections? Why do you have migraines and heart problems and kidney stones and glaucoma? We experience these things because we inhabit bodies that have been marked and marred by sin. Paul spoke directly to this when he said:
So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. (2 Corinthians 4:16)
Our outer self is wasting away. Our bodies don’t work correctly. They fall apart and fail us at the worst times. While we live in this fallen world, we live in bodies that are wasting away.
In Romans 8:22-23, Paul wrote:
For we know that the whole creation has been groaning together in the pains of childbirth until now. And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies.
Along with the rest of creation, we eagerly wait for the day when Christ will return and we will receive our new, redeemed, resurrection bodies.
Until the day Jesus returns, I will live in a body that does not function as God originally intended. My brain, which is a key, central, integral part of my body, will not function correctly. Chemicals will become imbalanced. Serotonin will not be properly absorbed. Norepinephrine will be unevenly distributed. Synapses won’t fire correctly. My brain, just like every other part of my body, is prone to illness.
I would argue that if we truly believe in total depravity, then we must accept mental illness as a biblical category. If I believe that sin has affected every part of my body, including my brain, then it shouldn’t surprise me when my brain doesn’t work correctly. I’m not surprised when I get a cold; why should I be surprised if I experience mental illness? To say that depression, anxiety, ADHD, bipolar and every other disorder are purely spiritual disorders is to ignore the fact that we are both body and soul.
Mental illness is not something invented by secular psychiatrists. Rather, it is part and parcel with living in fallen, sinful world.
