Leviticus - really??

Here's the link to the Sermon: The exciting Gospel according to Leviticus 23 

Instead of reading the whole passage through first, take the chapter and discuss:
 

1. The Sabbath - how does this compare with The Lord's Day for Christians?
2. For each of the feasts talk through:

          a) what the original purpose was;
          b) what the prophetic purpose is;
          c) how is understanding this relevant and useful for us today.
