"how do i answer someone who says that curing disease is against God’s will because, what if He intended the person to die?"
This is the Argument by Christian Scientists : If God don’t heal ya, then you were meant to Die.
Well, the Bible is full of times when people relied on MORE than God’s Will to cure their illness.
For instance, there was the Woman who touched Jesus on his cloak. She had been to all kinds of Doctors for 18 years.
So, if it is NOT pooh-pooh’d in the Bible, then God probably doesn’t care if we receive Medical Treatment.
If that person gets a Headache, and refuses to take an Aspirin, that’s fine with me.
If that person chooses to forgo Cancer treatment … Well, it was Nice knowing you.
As far as Cloning is concerned, that person can just agree to NEVER be Cloned.
Abortion is a different matter. The Church has decided that Abortion is a BIG no-no.
These are all completely Optional, and are NOT meant to Cure a Disease.
"they compare it with abortion and cloning saying that if you intervene with God’s will in one area, you can do it with others."
Fine, they don’t need to have an Abortion, or Clone themselves (and do not need to lose any sleep over the fact that others might do it).
And, if a person claimed that he didn’t want Medical Care, it seems unlikely that the ONLY reason for it, is worrying about what God might say to him in the After-Life.
But, Hey, people do what people do. People believe what people believe.
This reminds me of the (real) OLD saying : If God wanted us to Fly, He’d have made us with Wings.
So, what if God’s Will is for everyone to WALK wherever they Go?
Every car driver, bus passenger, and airplane pilot are blatantly violating God’s Will.
The same thing occurs.
People don’t know what God’s Will is … and start to point at everything, and question it.
