The Bible teaches that God the Father provides all our needs to live a life of abundance. Every provision has already been provided (since the creation of the world), we just need to learn how to take hold of theses provisions, which are provided to us by grace, through faith. You see, in the kingdom of heaven, which is in the spirit of a believer has no lack or economic down-turns.
Read Matthew 6:25 "Do Not Worry", this may shed more light on the subject of having all your needs met. That's what economics is about, right? Meeting the needs of everybody.
It's called entering Gods rest. "Therefore, since the promise of entering His rest still stands, let us be careful that none of you be found to have fallen short of it. For we also have had the gospel preached to us, just as they did. But the message they heard was of no value to them (children of Israel), because those who heard did not combine it with faith. Now we who have believed enter that rest, just as God has said... " Hebrews 4
The Lord's work has been finished since the creation of the world. "On the seventh day God rested." Not because He was tired, it was because He was finished. That is why He knows the beginning and the end. From that time everything was put in perpetual motion, so to speak.
Those who seek and find the Lord will not be disappointed.
