Many on this board dismiss open air preaching [edited]. Anyways this is not my opinion, or the opinion of Comfort (although Comfort clearly says Jesus was a open air preacher) this is scripture that I am quoting. So whats your excuse now?
Matt 11:20-24 (NIV)
20 Then Jesus began to denounce the towns in which most of his miracles had been performed, because they did not repent. 21 “Woe to you, Chorazin! Woe to you, Bethsaida! For if the miracles that were performed in you had been performed in Tyre and Sidon, they would have repented long ago in sackcloth and ashes. 22 But I tell you, it will be more bearable for Tyre and Sidon on the day of judgment than for you. 23 And you, Capernaum, will you be lifted to the heavens? No, you will go down to Hades.[a] For if the miracles that were performed in you had been performed in Sodom, it would have remained to this day. 24 But I tell you that it will be more bearable for Sodom on the day of judgment than for you.”
