The Day of Atonement pictures the great atoning work of the sacrifice of Jesus Christ for all mankind. But it also pictures the defeat of Satan and his government by Christ, which must occur in order for Christ to reign as King of Kings and Lord of Lords over the same world once ruled by Satan. He will not go willingly and must be deposed by Christ. The symbolism of Leviticus 16 helps us understand the future of Satan and foretells what we read in Revelation 20:1-3.
