What does Les tell a friend who wants to start coming while he is teaching Revelation?
He advises holding the friend off until the class starts in Genesis, because he prefers people begin with Genesis and then come all the way up through the Bible. Starting late in Revelation, he says, is like entering a calculus class without fourth-grade arithmetic, since teaching is a progressive process.
Les explains that when he is in Old Revelation or something, and someone says they have a friend who wants to start coming, he tells them to hold the friend off until the class begins Genesis. He prefers that people start with him in Genesis and continue all the way up, because entering his line of teaching late in the New Testament is like a child entering a calculus class without ever having had fourth-grade arithmetic; it is a progressive process. He also notes that you do not want to push somebody out the door and simply say wait until Genesis.
