<p>3:10 <i>And the crowds asked him, saying: What then must we do?</i>- Luke phrases this in the same language he uses of the crowds who responded to Peter's preaching in Acts 2. The answer was the same- repent, accept Jesus as Messiah and be baptized. John saw the essence of the Christian gospel as just that, and it was essentially the same message taught by both John and Peter. </p>
