Thus could Ken Copeland write in his Laws of Prosperity, "Do you want a hundredfold return on your money? Give and let God multiply it back to you. No bank in the world offers this kind of return! Praise the Lord!” In this mentality, tithing is a financially responsible thing to do. It’s a show of faith and a shrewd investment alike, a wager on the idea that God acts in the here and now to reward those with both faith and a sufficiently developed work ethic.
