Please read Leviticus 16 in your Bible before reading any farther.
We must look at the two goats. One goat was sacrificed while the other was led into the wilderness. One payed for sin while the other had the sin cast upon its head. This is very important to understand. The sacrificial goat represented Jesus Christ while the Azazel or scapegoat represented Satan. So a part of the Day of Atonement is fulfilled in that Jesus Christ did die for the sins of the world and was raised the third day. However, has all of the sin been placed upon Satan yet? I would encourage you to read the booklet "How Seasonal Holy Days Reveal God's Plan" by Garner Ted Armstrong. I will include a link at the bottom of this article.
