I don't quite understand this.both our health and our illness could be a gift from God
I assume that your line of reasoning is that a "greater good" might come out of our illness, therefore it is a gift of God that we have the illness so that we can get the greater good.
Now, I agree that God can bring greater good out of an illness (Rom 8:28 ) but this is a far different matter than saying God struck us with illness to teach us something, or for some greater good.
Let me ask you this. Would God ever get us to sin for some greater good? What if an unsaved person commits murder and get sentenced to life in prison. while incarcerated, he gets radically saved through prison ministry. he evangelizes his cell block and many are saved.
Now- did God cause him to commit murder so that a greater good could result? obviously not. but God used the sin to bring glory out of a bad situation.
i think the same can be said for illness. God doesnt cause it, nor is he pleased about it (IMO). Therefore I think we should combat it. sickness and disease is not God's best for us. i dont think we should simply accept it. we are to fight against it, just like we fight against sin. why would we want to resign ourselves to sickness? Jesus never made anyone sick, nor did he tell them that their sickness was for some greater good (other than lazarus, but he raised him from the dead for goodness sake).
Do you see where I am coming from?
