If I try to make only enough money for my family' immediate needs, it may violate Scripture. ...Even though earning just enough to meet the needs of my family may seem non materialistic, it's actually selfish when I could earn enough to care for others as well.
The more you give, the more comes back to you, because God is the greatest giver in the universe, and He won't let you outgive Him. Go ahead and try. See what happens.
