Day of Atonement
The Hebrew word kippus means covering or atonement. In the Old Testament sacrifice system, the sins of the high priest and the sins of the people were "covered" by the blood of bulls and goats.
This covering was effectual, yet temporary, in that it needed to be reapplied every year at this time. Even so, the Lord considered the people cleansed within the ordained framework of the sacrificial system, before Yeshua came to earth and offered Himself.
And the Lord spake unto Moses, saying, Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the Lord. And ye shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the Lord your God.
We must learn to deny ourselves, to become poor in spirit and to deny the urgent demands of our fleshy nature. This refers to denying pride and self-importance, and taking on a humble and servant-like attitude. It also includes some physical self-denial, although it is natural to desire food, comfort, shelter, sleep and physical safety. It goes against our instincts to deny ourselves through fasting and self-sacrifice. However, this is the cost of discipleship.
The Day of Atonement speaks of sanctification, a lifestyle in which our flesh comes into alignment with our spirit, rather than the other way around. It calls the Bride to a life of discipline and purpose. The sanctified life is a life dedicated to serving the Lord, not one filled with our own agendas, entertainment, and ambitions. The higher the calling, the higher the price one must pay.
