What is the importance of yom Kipper day?

Answer 1

Yom Kippur or the "Day of Atonement" is described in Leviticus 16. It is the only commanded "fast" for God's people, among all of His seven annual Holy Day "feasts" [Lev.23].

It pictures "Christ laying all the sins of the world upon the head of Satan upon His return to earth." Leviticus 16 describes the "sacrificial details" of the event... and Revelation 20:1-3 pictures the tail end of its prophetic fulfillment, with Satan being cast out: "...that he should deceive the nations no more, till the thousand years should be fulfilled...".

The two he goats in Leviticus 16 picture Jesus and Satan. The "slain goat" is Christ. The "risen Christ" is the high priest, who then "goes to heaven" with the slain goat's blood" [into the Most Holy Place, where the Ark of the Covenant"... the throne of God... was]. There, the high priest makes intercession for the sins of the people... and then... RETURNS FROM HEAVEN.

Then, the "azazel" goat [Lev.16] is captured and secured by a strong man:

"...I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand. And he laid hold on the Dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years..." (Rev.20:1-2).

The "returned from heaven" high priest [Lev.16] then lays his hands on the head of the "azazel" goat:

"...Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness: and the goat shall bear upon him all their iniquities unto a land not inhabited: and he shall let go the goat in the wilderness." (Lev.16:21-22)

"...and cast him into the bottomless pit, and shut him up, and set a seal upon him..." (Rev.20:3).

The Day of Atonement is a "prophecy" that God has given His people to let them know that part of His plan of salvation. And each phase of God's plan will be fulfilled, one step at a time. Just as Jesus fulfilled the Passover, which remains a solemn "memorial" to His people until He returns with the Kingdom of God... the observance of which He changed that night in the symbols of the "bread and wine."

"...this do in remembrance of Me." (I Cor.11:24)

The Day of Atonement is a looking forward in hope to the day when Jesus returns [on the Feast of Trumpets - the next hope of His people]... whereupon, Jesus will divest Himself, nine days later, of all the sins that He's borne for us since that Passover... and begin to remove evil altogether from the earth, culminating with the "Last Great Day" -- the seventh and final biblically commanded annual Holy Day feast of the Lord, Jesus Christ, which pictures "Judgment Day."
