DEUTERONOMY 15:10 (NIV)
Give generously to him and do so without a grudging heart; then because of this the Lord your God will bless you in all your work and in everything you put your hand to.
One of the biblical principles that goes with acquiring and managing wealth is the willingness to share it. God promises his blessing to the person who is concerned about others. God is not a heavenly vending machine, dispensing $100 bills when you give $20 to the church. But when you put God first in your life and business affairs, you can take seriously these kinds of promises.
