"Then Jesus spoke to the multitudes and to His disciples, saying: 'The scribes and the Pharisees sit in Moses' seat. Therefore whatever they tell you to observe, that observe and do, but do not do according to their works; for they say, and do not do.'" (Matt. 23:1-3)

A certain fountain pen salesman persuaded a merchant to order 500 dozen pens. He was writing the order in his notebook when suddenly the merchant exclaimed, "Hold on! I'm canceling that order!" Then he turned to wait on a customer. The salesman left the store perplexed and angry. Later, the merchant's bookkeeper asked, "Why did you cancel that fountain pen order?" "Why?" responded the merchant, "because he talked fountain pens to me for half an hour, using a number of forcible arguments, and then booked my order with a lead pencil. His practice did not agree with his instruction."

Let us practice what we preach and preach what we practice.
