A son asks his father if he can start using the car more often. The father said, "I'll give you 3 weeks to improve your grades, get a haircut, and read your Bible more often."
3 weeks later, the father and son talk again. The son says, "I've done what you asked and I would like to borrow the car now.
The father says, "I've noticed you've been coming to church on time and you've been reading your Bible, but you still haven't cut your hair.
The son replies, "I've been thinking while I've been reading the Bible. All the men in the Bible had long hair, including Jesus."
The father replied, "Did you also notice they walked everywhere they went?"
