Why did Les leave Iowa and move to Oklahoma in 1975?

Les explains that the home Bible study began on the first Friday night in September 1970 with four people, and with Iris and him that made six. By Thanksgiving it had grown so large it had to be split, and within a couple of years classes were held every night of the week, along with his Sunday school class and a Sunday night class at their church. Then in 1975, just out of the blue, the Lord had other plans. Les says the Lord uprooted them from Iowa and brought them to Oklahoma. He notes that he never went out to open something himself; he waited until someone asked him to come and start a class. The same pattern continued in Oklahoma, and later the same happened with television.
