Hi,
I'm going to reply to Question 2: Is the "Prosperity Message" biblical?
Yes, it is.
Nevertheless, this is one of the most misunderstood topics in the Bible among modern people.
It's not money and wealth in itself that's problematic.
The problem is the LOVE of these things.
Why is it a problem? For many reasons, but two are: 1) It leads to greed, one of the seven deadly sins. 2) It's preventing us from doing good with our means because we want all by ourselves.
A short, but in my opinion, essential distinction.
