Faith comforts, and motivates, and can provide insight. That matters, because it affects decisions. But it doesn’t directly affect or circumvent the laws of the natural world. Including the law of supply and demand.
If you follow certain rules and establish certain habits, you’ll likely do well in this world. Where and when you were born matters a lot too. Not to mention genetics. While it’s nice to believe that such factors can be overridden by supernatural forces, activated through faith, we’re beyond that now. The evidence is overwhelming.
We can still believe in God and we can still pray, but it’s clear that God made the rules of this life in such a way that belief isn’t enough. We also must do. And the doing needs to be done intelligently.
