Cynthia Flynn explores the concepts of tithing, seed time, and harvest in this book that reveals how God can bring you spiritual and physical riches. While it may be hard to believe, when you give 10% of your salary to the church, God will take the 90% you have left and make it go further than the original 100% - a lesson that Perry Hayden and Henry Ford learned during a farming experiment in Tecumseh, Michigan. The author did not fully comprehend this until 1984, when she heard giving expressed as a challenge. The concept intrigued her even more when she heard a pastor say that God actually wants us to test Him on this idea. Later, Flynn discovered one of her friends who believed in tithing did so for the express purpose of getting her a job. That meant when her friend wrote out the check, she laid her hands on it and said, "This is Cynthia's new full-time sales job (seed) that comes with a salary better than she has ever dreamed of (what it produces/harvest)." More than thirty-five years later, the author is still tithing, setting bigger goals, and achieving them with help from the Lord.
