Indeed, God is debtor to NO man. But the prophet says specifically that God makes peace and creates evil. So the whole "health and wealth" label is full of baggage that has to be neatly unpacked to be properly assessed. The prosperity gospel being taught today is right out of I Timothy 6:5 - it's almost like they are reading from the script!
That said, God certainly does prosper the righteous. So it shouldn't be assumed that if someone is in right standing with God that they are poor or struggling. Jesus promised the disciples who followed Him wealth, lands and family both in this age and the age to come (Matthew 19:29 and Mark 10:29-30). But note the prerequisite - to leave all that they have to follow Him. That's what He challenged the rich young ruler about. And if some don't receive a dime from God in this life, but are faithful in following Him, there is no doubt that their reward in heaven. This reward is for those that suffer persecution for Him (e.g. Matthew 5:12). Paul said that he suffered the loss of all things for the sake of Christ Jesus his Lord (Phil 3:8). But there are many that never received even what was promised while they were here on earth (Hebrews 11:13). Abraham believed God because he trusted God - that He would provide, even in the face of no natural fulfillment. But God told Abraham one key thing that differentiates the prosperity gospel from God's faithfulness to provide "more than we can ask or think". It was this :
After these things the word of the Lord came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.
Genesis 15:1
God HIMSELF was to be Abraham's reward. Not that he wouldn't receive much while on earth, but that the reward for Abraham was entirely wrapped up in God. His promise, His presence and His provision. They were all part of the same thing that ultimately couldn't be severed from God. So to Abraham, whether or not he received this kingdom while on earth or not was not the point - it was that God could be trusted, God promised and so God will provide. That's the only reason he was willing to sacrifice his miracle son - he reasoned that God could raise him up. But that wasn't necessary. Abraham thought God "could" do things one way but God did things another way. His way was so far removed from what Abraham could conceive. But Abraham believed God.
Abraham still had much in the way of natural possession, but that is not what he was after. It was incidental in view of what God really had for him.
That is NOT the message of the prosperity gospel because their reward is utterly natural, perishable and full of corruption.
Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
For where your treasure is, there will your heart be also.
Matthew 6:19-21
