If everything has a purpose then evil doesn't exist

[Mister Agenda]

I think our point is that the child with cancer in your scenario is just a means to the end of testting their parents. In your scenario, the baby was born and got cancer in order to be a test for its parents. The idea is unconscionable.

where does my senecio say God gave the baby cancer to test the parents?

I said or rather referenced what Jesus said that This world is not apart of God's immediate Kingdom. and His will meaning God's will is not followed on Earth as it is followed in Heaven.  This makes Sin and Satan the rulers of this world. I also said the reason we get cancer is because like a copy of a copy of a copy degrades over time so too does the human genome degrade over time.

This degradation is the direct result of the introduction of sin into God's creation. So if you want to be mad at someone be made at the current ruler of this world.

It's Winterhold's scenario. I understand your view is different from his.
