Until the time of John the Baptist, people had to obey the Law of Moses and the Books of the Prophets. But since God's kingdom has been preached, everyone is trying hard to get in.
The food that you put into your mouth doesn't make you unclean and unfit to worship God. The bad words that come out of your mouth are what make you unclean."
When John the Baptist showed you how to do right, you would not believe him. But these evil people did believe. And even when you saw what they did, you still would not change your minds and believe.
Jesus went all over Galilee, teaching in the Jewish meeting places and preaching the good news about God's kingdom. He also healed every kind of disease and sickness.
The man talked about it so much and told so many people, that Jesus could no longer go openly into a town. He had to stay away from the towns, but people still came to him from everywhere.
