Why does Les like to teach these things?

Les explains that the reason he likes to teach these things is to show how intrinsically and beautifully all of the Bible puts together. Everything fits from Genesis to Revelation, and everything is so programmed that no human could have ever dreamed it up. He then points out that there are 7 of Paul's Epistles written to the Church, called the Church Epistles. Paul did not sit and try to divide his letters to come up with the number 7, which is God's perfect number. Instead, Paul just wrote those letters as it was appropriate, and it fell out that there were 7 written for the Church.
