There is a sanctuary in heaven, the true tabernacle which the Lord set up and not man. In it Christ ministers on our behalf, making available to believers the benefits of His atoning sacrifice offered once for all on the cross. He was inaugurated as our great High Priest and began His intercessory ministry at the time of His ascension. In 1844, at the end of the prophetic period of 2300 days, He entered the second and last phase of His atoning ministry. It is a work of investigative judgment which is part of the ultimate disposition of all sin, typified by the cleansing of the ancient Hebrew sanctuary on the Day of Atonement. In that typical service the sanctuary was cleansed with the blood of animal sacrifices, but the heavenly things are purified with the perfect sacrifice of the blood of Jesus.
