A slightly flippant response could be that Paul could have made his point much more simply had he read his Hebrew scriptures. It is mainly when the going gets tough that the people of Israel turn to YHWH. As soon as things things are going smoothly, their faith goes downhill. Scripture itself shows clear evidence of a strong negative correlation between faith and wellbeing.

Nothing new under the sun. I would like to see someone do a paper instead of a pamphlet.
