Bearing Fruit

The words of John the Baptist when he called the crowd that came out to hear him.  John called them "a brood of vipers".  "Who warned you to flee from the wrath to come"?  "Bear fruits in keeping with repentance".  

The crowd asked him "what then shall we do"?  John answered and said, If you have two tunics, share with him who has none.  John told the soldiers "to be content with your wages." John told the tax collectors to "not collect more than you are authorized to do".

What would John say today?
