Acts 28

I was reading in Acts 28 today and Paul quoted Isaiah when he was talking about the Pharisees who, "Although hearing they do not hear and while seeing they do not see..." I think its crazy that some people hear the gospel and some people see the gospel in action but still do not believe nor do they obey. Why? Check out Matt 13:10-16 and write out 30 observations on the text. Whats Jesus talking about and what is the reason for people not hearing and understanding? Your observations may be questions or just obvious facts about the text. Try to find out everything about it.
