Christ in His Sanctuary : Types in the Sanctuary Service

Arguments drawn from the Old Testament types also pointed to the autumn as the time when the event represented by the “cleansing of the sanctuary” must take place. This was made very clear as attention was given to the manner in which the types relating to the first advent of Christ had been fulfilled.
The slaying of the Passover lamb was a shadow of the death of Christ. Says Paul: “Christ our Passover is sacrificed for us.” 1 Corinthians 5:7. The sheaf of first fruits, which at the time of the Passover was waved before the Lord, was typical of the resurrection of Christ....

These types were fulfilled, not only as to the event, but as to the time. On the fourteenth day of the first Jewish month, the very day and month on which for fifteen long centuries the Passover lamb had been slain, Christ, having eaten the Passover with His disciples, instituted that feast which was to commemorate His own death as “the Lamb of God, which taketh away the sin of the world.” John 1:29 That same night He was taken by wicked hands to be crucified and slain. And as the antitype of the wave sheaf our Lord was raised from the dead on the third day, “the first fruits of them that slept,” 1 Corinthians 15:20 a sample of all the resurrected just, whose “vile body” shall be changed, and “fashioned like unto His glorious body.” Philippians 3:21.
In like manner the types which relate to the second advent must be fulfilled at the time pointed out in the symbolic service. Under the Mosaic system the cleansing of the sanctuary, or the great Day of Atonement, occurred on the tenth day of the seventh Jewish month (Leviticus 16:29-34), when the high priest, having made an atonement for all Israel, and thus removed their sins from the sanctuary, came forth and blessed the people. So it was believed that Christ, our great High Priest, would appear to purify the earth by the destruction of sin and sinners, and to bless His waiting people with immortality. The tenth day of the seventh month, the great Day of Atonement, the time of the cleansing of the sanctuary, which in the year 1844 fell upon the twenty-second of October, was regarded as the time of the Lord's coming. This was in harmony with the proofs already presented that the 2300 days would terminate in the autumn, and the conclusion seemed irresistible....
Carefully and solemnly those who received the message came up to the time when they hoped to meet their Lord. Every morning they felt that it was their first duty to secure the evidence of their acceptance with God. Their hearts were closely united, and they prayed much with and for one another. They often met together in secluded places to commune with God, and the voice of intercession ascended to heaven from the fields and groves. The assurance of the Saviour's approval was more necessary to them than their daily food; and if a cloud darkened their minds, they did not rest until it was swept away. As they felt the witness of pardoning grace, they longed to behold Him whom their souls loved.
