Well, this can be taken as a joke but I think it makes on sit up and think.
A young boy had just gotten his driving permit. He asked his father, who was a Minister, if they could discuss his use of the family car. His father took him into his study and said, "I'll make a deal with you. You bring your grades up, study the Bible a little, get your hair cut and then we'll talk about it."
After about a month, the boy came back and again asked his father if they could discuss his use of the car. They again went into the father's study where the father said, "Son, I've been very proud of you. You have brought your grades up, you've studied the Bible diligently, but you didn't get your hair cut."
The young man waited a moment and then replied, "You know, Dad, I've been thinking about that. You know Samson had long hair, Moses had long hair, Noah had long hair, and even Jesus had long hair..."
The Minister said, "Yes, and everywhere they went, they walked."
