Christians!? whats up with this?

You cannot take verses out of the Bible and expect to understand them on their own. You need to view the book as a whole, to see the amazing story of God. You are quoting verses from the Old Testament. These sacrifices, etc. are no longer required of followers of Christ. Christ was the perfect sacrifice, whose death paid the price for the sins of all humanity. All one needs to do is accept that gift. Read the Bible cover to cover, join a Bible study, and you will begin to see the threads woven through it. It's an amazing Story!
