Changing Poison into Medicine
If God created the world and everything in it in perfection, where did disease, sickness and death come from? It's clear from the Bible that God did not intend for humans to suffer disease and death. However, when humans withdrew their love from God by disobeying Him, they caused the nature of creation to be changed.
It appears that it would take only small, subtle changes in chemistry and biology to change helpful and good organisms into deadly organisms. For example, botulism is a fatal food poisoning caused by the botulinum toxin produced by a microbe growing in food. Botulinum is the most powerful toxin known to modern science.
Medical researchers have discovered that very tiny amounts of botulinum toxin may be safely injected into spasming muscles to stop involuntary spasms. These small doses stop involuntary nerve impulses without interfering with voluntary use of the muscles. This therapy promises to help people who suffer from involuntary clinching of eyelids, throat, misaligned eyes, stuttering and the cramps often suffered by musicians, writers and typists. Therapy appears to work for several months before it must be repeated, and there appear to be no side effects. This treatment is not theoretical; doctors are being trained in using it right now.
So a dangerous poison can be medicine. Perhaps this hints at a purpose God may have originally intended for the botulism microbe.
