I have read a bit of your material and see that you know where you stand and that a wave or two don't bother you...
Having said that I would like to pitch one at you.
If antibiotics have healing powers then put some on a tear of clothing and it should mend the tear.
We would say that is silly because there is no life in clothing - so there is nothing to heal - and of course that is right.
So what is healing - but a life process.
In contrast then, what is sickness but a perversion disrupting the life process.
An antibiotic then simply creates an environment that inhibits or prevents that particular perverted process from continuing - and if the given life of the host is strong enough it will continue to reproduce the intended cell structure we would call healing.
That is not quite the case. Sickness is the result of sin. In general, sickness is part and parcel of life in a broken and fallen world. It’s part of the fallout from our collective rebellion against God, and in that sense is indiscriminate.
Antibiotics are given to combat "infections". I think that it is short sighted to think that modern medicines such as antibiotics do not have healing qualities. I understand what you are saying, however for the process of healing to take place, God has given man the ability to create medicines that allow such a thing to happen.
If a man has an infection from a cut on his leg and is not treated with antibiotics, he will loose 1st his leg and then his life. The term "sawbones" was given to military doctors who had to cut off legs and arms to keep the victim alive from infections before antibiotics were created.
I believe that what you are saying is that If, the body’s infection-fighting mechanisms are able to keep the infection from spreading, and then win the battle, the infection will be killed.
What I am saying is that antibiotics improve the likelihood this scenario will occur and history proves that fact.
Bless you my friend!
