I am no expert but the current Prosperity Gospel being taught is so wrong on so many levels.
We are told not to seek riches in this life.
Being Blessed, does not always mean monetary rewards in this temporary state of being.
A Blessing is also a learning experience that we take to Heaven - I don't know why because I am but a humble human.
To be Blessed means that you are going through a refining - going through a trying experience that will make you a kinder more understanding person - more Christ like.
Read Chapter 1 of James, it is quite revealing.
I don't believe that using just one verse of a chapter is a good indicator of what the writer is trying to say. One verse can be used to justify behavior, you must read if not the whole chapter, then a few verses ahead and beyond. You get a much better
picture of what is being said.
Prosperity Gospel teaching uses the Bible in that way - they are then able to justify
what ever they are are saying.
I have some research writing on the Prosperity Gospel and why it is so wrong.
Let me know if you are interested and I will email it to you, it is quite lengthy.

Ecclesiasties or any other book contained within... I would believe Harry Potter first!! And am a well informed as well as educated adult to know the difference between Fiction and Non-fiction. If I want to hear a sermon on wealth I'll rediculously pay out to others for their promises of false hopes. The reality is not to
hide behind empty promises or promotional propaganda
