I have often remarked in reference to verse 28, "If one part suffers, all the parts suffer with it", no we don't. I say that because I know of persons with disabilities who have been seemingly cut off or excluded from the Body of Christ, the church, and we don't seem to be participating in their suffering. A colleague of mine, however, said to me that we are actually suffering, but we just don't realize it. As he shared that perspective with me, I immediately thought about leprosy where the sense of pain is lost. But as I think about it, it is more than that perhaps. How can I be suffering and not even know it?
Maybe it's because I have lived my life in a suffering state for so long, I don't know what it is not to be suffering in a particular way. Suffering in that manner becomes the norm for me. So for example, I have lived my life since age 5 wearing glasses. I have seen the world, looking through lenses for 55 years. I have on some level become used to the scratched, smudged experience of seeing the world. I don't realize my impaired vision from wearing glasses until I get new glasses. Then for a while I have the clear vision experience (although I still am living my life feeling like I am looking through a window rather than having an unobstructed view of the world). But after a while, I ultimately go back to the imperfect, scratched, smudged glasses experience. I get to the point where I don't know what it is like to not be that way. But in regards to this Bible passage, how might the body be suffering and know knowing it?
Maybe I am suffering from accepting living in a form of the Body of Christ where we don't love our neighbors. I could live in a beautiful, though demanding, social environment but I don't because I have become accustomed to the way the social environment has developed and found its way into the Church. Even though I may have an idea of what life might be like if I and the rest of the body loved our neighbor I have never fully experienced it. So I suffer though I don't know what it is I am missing.
Then, maybe I suffer from missing out on what the social environment might be if everyone was provided the opportunity to experience their gifting. We speak in the Christian faith of purpose in what God does. So in reference to disability we would say that God either causes or allows disability. However, if the purpose in the way people are, the giftedness in what they are as they are is not given opportunity for expression then I suffer from an incomplete expression of the sovereignty of God. It would be as if there were no musicians in the world because people with characteristics leading them to become musicians were excluded from us. I don't know what I am missing because a particular gifting set (potentially) is never expressed. Once again, we suffer from missing out on that set of gifts. We suffer from no music because we have never had music. If we had music and then had it taken away, then we would suffer from the beauty missed. But if we never had music, we are suffering from something we were intended to experience but have never experienced because of our exclusive choices.
We also suffer from living in disobedience. Of course we are all the victims of our sinful condition in myriad ways, most of which we probably have no idea about. But with each step with which we grow in obedience, we may find out how we have been suffering, what we have missed out on by living in our disobedience. We experience this personally but we also experience this corporately in a similar way. When we as a group make decisions that are sinful in nature, like excluding people or showing favoritism, we lose something. We suffer something, although we may not realize what it is.
So yes, I agree with my colleague. Whether we realize it or not, we do suffer in ways we were not intended to suffer. Perhaps our awareness of these things will cause us to remember the pain, re-experience the pain and move away from the behavior that causes the pain.
