That's the problem though. Those same doctors will medicate and suppress any person they are able to, who claims to have a relationship with God. They think they are doing good, but their ways are ultimately destructive. Did you listen to those poor owls? How on earth can any person do a thing like that? Is that what God would do?
You might be looking at just those situations where it is discovered that doctors are not as ethical as they should be and has resulted in harming people. And although it's true that some doctors use their medical for profit and greed, others really want to help cure people. There is also the problem with government interfering with the medical community to gain a financial advantage, but while their wrong efforts hurt some, others are helped. So God will take the bad and turn it into good.
For example, the AIDS virus in the United States killed thousands, and thousands of people. Why do you think doctors continued to research and look for a cure? If these doctors and scientist did not care about humanity, they would have just forgot about it and let everyone die. But no! They continued to look for a cure. Although there is still no cure, from their research they have discovered a medication that can decrease the TCells to where the virus cannot be passed to another person. That medication is available in the US.
Now look at Africa and the Aids virus. There are millions upon millions of people in Africa that died from the Aides virus down to the innocent children. Do you think God want to see this? No he doesn't. But there is a problem in Africa with the government stopping life saving drugs that can save the people from not just Aides, but all sorts of diseases. But, only a small portion of villages received medicine and the others are left to die. So now there are the "Doctors Without Borders" here in the US that travel to Africa and other third world countries to help with the problem of diseases that's killing the people, and the lack of medicine and medical personnel. Some of these doctors have risks their lives to save these people. How many children are dying right now from drinking contaminated water? What should people do who see such a thing? There are people, scientist working right now to create drugs to de-contaminate the water so that these children will have fresh water, and live and not die. So who put it in these doctors hearts to travel from their safe homes to risk their lives to save these children?
So what I'm getting at is Satan is responsible for all of the diseases and dying of God's people.' Satan is also responsible for corrupt doctors and corrupt government. But God in His love for His people have given man knowledge to find these cures, and although we have to contend with corruption, there are still millions of people helped.
If Christians possessed the faith that God say we are to have, Christians would be able to heal. But there is a famine in the land. Faith is waining. So our loving God has stepped in and is doing what we cannot do by giving doctors the ability to find cures and develop medicine.
