Why does Les Feldick do this Bible teaching ministry?

Les explains that they are not in this ministry for money. They freely allow people to dub their own tapes and make copies of the little books. The only reason they are doing this, he says, is the same burning desire the Apostle Paul had to see lost people saved. Les also notes that many times he wonders what he has gotten into because he is still a full-time rancher with all the ranch responsibilities, but the Lord has given this ministry, so they have to use it for His glory. He also mentions that mail time and letters of encouragement are a high point of their day.
