Good post! However, I would say that I disagree with most of it. I do like the fact that it is well thought out using some examples from the Word.
Let me ask you some questions:
You said, "The promises of wealth in the OT were a part of old covenants made to specific people" -
Question: How are you arriving at the "specific people". Under the Old Covenant, while God made covenant with individuals they were not limited to those individuals. The covenant God made with Noah is still active today, etc.
You said, "with attendant conditions and cannot be automatically appropriated to us today as NT believers."
Question: How can that which was a foreshadow of what to come not be appropriated to us today as NT believers?
You said, "Thus their wealth was more of a socialized government of sorts rather than extravagant personal wealth." How do you differentiate between the promise of God like in
Deut 8:18, and
Deut 28 which talks of the blessings of obedience and make it a socialized government?
Final question: While I agree that the pursuit of wealth for the American dream is not biblical, how do you handle scriptures like
Galatians 3:13-14, that deals with the blessing of Abraham which included wealth.
2 Cor 9:8 that promises the sufficiency to abound to every good work?
