In the New Testament, Jesus clarified what prosperity really means.
John 10:10
The thief comes only to steal and kill and destroy; I have come that they may have life, and have it to the full.
John 6:63
The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit[
a] and life.
What the devil used to tempt Jesus with: lusts of the flesh like material prosperity
What Jesus meant by 'full of life' or prosperity: Things that concern the Spirit. because the flesh counts for nothing.
Prosperity have entirely different meanings between Jesus and the devil. The latter concerns material prosperity only and any counterfeit notion of spirituality that led to the fall of the Pharisees.
The devil comes only to steal and kill and destroy and his favorite weapon is worldly wealth. It steals - exploits the weak for the cheap labor and desperation, kills - the environmental impact of money-making, and destroy - by blinding you from the truth.
Abraham became rich for a reason, he would have become the foundation of a great nation. Joseph saved so many lives. But wealth and power nearly destroyed King David. It almost destroyed King Solomon until he lost everything. Only after he lost everything that King Solomon received real wisdom from the Lord - Ecclesiastes - but Christians would rather read Proverbs. King Solomon's worldly wisdom BEFORE his redemption.
It all ended in the New Testament. We have no longer have any purpose to live a life of privilege as it will only blind us from the truth. Everything became a test. Even the Bible became a test.
Of course, most Christians don't know. They have more time with worldly things than seeking the truth. Fellowships with equally deceived Christians who are the only ones who can understand their worldly love because that's where their heart really is.
