One of the scariest things that tested my faith was to not use Antibiotics after major surgery at the first of this year. I fell strangely and broke my upper arm and had to have emergency replacement surgery. After all of that, if an infection would have happened, I could have lost my arm.
I tried really hard to do what seems best for myself, but being in an emergency situation I had to do something.
I did do pain meds in the beginning and my therapist and doctor insisted that I take them for my success in physical therapy. The funny thing is that I found out that these meds actually made my recovery worse. My doctor had a genetic test run on me and found that I do not do well with certain pain medications. I told them that I didn't feel as though I was in any pain...but they though my lack of movement was due to pain stopping me.
As soon as I stopped taking the pain meds, I was making great gains in my health. I was able to move and build strength. Later I was told that my strength in my broken arm was greater than normal for someone my age. If I had listened to them and stayed on the meds, I doubt I would be able to say that right now.
So I understand what you are saying. And yes, that may be part of the polluted world that scripture spoke of, but I think there is much more to it than that. All sins need to be accounted for. And since we don't always know how we contribute to all the sins in this world...we need a Savoir to help us find the Way. Saying yes to His Truth....His Life...His Way.
