Read Psalm 35:9

Nothing physical touches the soul. Nothing external satisfies our deepest inner needs. 

Remember that! The soul belongs to God. He alone can satisfy us in that realm.

The soul possesses an inescapable God-shaped vacuum. And not until He invades and fills it can we be at peace within—which is another way of saying, "If God isn't in first place, you can't handle success." 

If God fills your soul, if God fills your mind, if God satisfies your spirit, there is no problem whatsoever with prosperity. You've got it all put together. Your priorities will be right, and you will know how to handle your life so you can impact the maximum number of people. 

If He prospers you, if He entrusts you with material success and you continue walking with Him, God can use you mightily in His plan. 

Furthermore, if you lose it all, He can give you what it takes to handle the loss and start all over again.
