A young boy had just gotten his driver´s permit and inquired of his father, an evangelist, if they could discuss his use of the car.
His father said I´ll make a deal with you. You bring your grades up from a C to a B average, study your Bible a little, get your hair cut and we´ll talk about the car."
Well, the boy thought about that for a moment, and decided that he´d settle for the offer, and they agreed on it.
After about six weeks they went into the study, where his father said, "Son, I´ve been real proud. You brought your grades up, and I´ve observed that you have been studying your Bible, and participating a lot more in the Bible study groups. But, I´m real disappointed, since you haven´t gotten your hair cut."
The young man paused a moment, and then said, "You know, Dad, I´ve been thinking about that, and I´ve noticed in my studies of the Bible that Samson had long hair, John the Baptist had long hair, Moses had long hair and there´s even a strong argument that Jesus had long hair."
To this his father replied, "Did you also notice that they all walked everywhere they went?"
